Why OpenAI Video Surfaces Show Spinners and “Stuck Jobs”

Products such as Sora—and other OpenAI experiences that surface generated or fetched video—stress the network differently from lightweight chat pages. The interactive UI might load from one cluster while authentication, billing checks, feature flags, job queues, upload slots, progress websockets, and object fetchers each negotiate their own HTTPS sessions. Many of those legs terminate on vendor-controlled names, but several may ride third-party CDN fronts that do not obviously share a single .openai.com suffix in your mental model. That split is exactly where split routing pain appears: the gallery renders, yet the first large segment never starts; the timeline marker advances in the UI while byte ranges stall; or the account header works while media thumbs stay gray.

If you already stabilized text-centric OpenAI pages, the baseline ideas are the same—see ChatGPT web and OpenAI domain rules for that foundation. Video flows add two practical wrinkles: long-lived connections with higher throughput expectations, and more hostnames that look unfamiliar in DevTools because they belong to generic edge networks. Clash still decides each TCP session’s outbound policy independently; half the names on AI_PROXY and half on DIRECT produces the same user-visible “broken product” symptoms as classic chat-page failures, only louder because progress bars make the stall obvious.

This article assumes you may lawfully run Clash, use the service, and inspect your own traffic. Embedded in many workplaces and campuses, proxy policies may forbid that entirely—this guide is not a waiver.

ℹ Instrument first: export failing hostnames with timestamps from the browser Network panel (or an equivalent trace), then align each hostname with a Clash log line showing the matched rule and policy. Spinners without evidence are configuration roulette; spinners with a hostname list are engineering work.

Split Routing: One Policy Slice for OpenAI Apps, APIs, and CDN Legs

The maintainable pattern is one dedicated policy group—call it OPENAI_STACK, AI_MEDIA, or extend your existing AI_PROXY—and route every hostname your traces prove participates in the session through that group until you have a cleaner taxonomy. “Cleaner” can mean separate groups later (strict API-only paths versus blob CDN legs), but premature micro-slicing before you can observe traffic usually reintroduces holes.

Keep domestic and low-risk destinations on DIRECT as usual; the win is not global tunneling but completeness inside the vendor slice. For structure and naming habits that age well, pair this with rule routing best practices so suffix bundles stay readable when you merge subscription lists with hand-maintained fallbacks.

When you import remote rule sets, treat “OpenAI” categories as a starting point, not a guarantee. Media stacks evolve faster than static lists; expect surprise subdomains after product updates. If you subscribe to large community providers, diff updates occasionally—an over-broad REJECT or a misplaced DIRECT catch can starve a CDN mid-download exactly like an adblock false positive.

Running Clash on more than one device? Mirror the same OpenAI slice everywhere you log in. Chasing “account” issues that are actually inconsistent routing between laptop and phone wastes hours. Choosing a client with log visibility and stable releases makes that discipline realistic.

Large Media, Throughput, and What “CDN-Friendly” Nodes Mean Here

Text payloads forgive high latency; multi-megabyte segments do not. Even when every hostname is classified correctly, an undersized relay, aggressive QoS, or an exit region with poor peering to the vendor’s edge can present as timeout storms or players that never leave the buffering state. Think in terms of sustained throughput and packet loss, not only “can I open google.com.”

The debugging mindset overlaps with other media-heavy stacks. Our guides on Hugging Face downloads and CDN split routing and YouTube buffering and streaming routes use different brand names but the same lesson list: cover blob hostnames, avoid blackholing generic CDN names, and pick exits that tolerate long HTTP bodies.

If you have multiple nodes inside the policy group, prefer health checks that reflect TLS reality—not only ICMP echo—so flaky relays stop winning. Sometimes the “right” domain rules still spin because the exit itself is degrading mid-transfer; rotate after you rule out policy misses.

DOMAIN-SUFFIX, Rule Sets, and Curated Providers

DOMAIN-SUFFIX,openai.com,OPENAI_STACK remains the workhorse because subdomains proliferate. Add parallel suffix rows for properties your traces show in 2026-era sessions—commonly including chatgpt.com and static delivery names such as oaistatic.com when your network sees them. You may also encounter short-lived marketing hostnames or identity partners; capture them from real failures instead of guessing from blog posts that will age out.

Rule providers automate refresh: Clash pulls remote YAML or binary rule bundles on a cadence you define, keeping pace with vendor expansion. The supply-chain caveat is unchanged—verify that a popular bundle does not quietly REJECT or mis-route a shared CDN used by your media legs. Maintain a minimal emergency profile you can load offline when a provider ships a bad revision.

Illustrative YAML fragment (names are examples—verify in your traces)

rules:
  - DOMAIN-SUFFIX,openai.com,OPENAI_STACK
  - DOMAIN-SUFFIX,chatgpt.com,OPENAI_STACK
  - DOMAIN-SUFFIX,oaistatic.com,OPENAI_STACK
  - GEOIP,CN,DIRECT
  - MATCH,DIRECT

If your default MATCH is DIRECT and a new hostname appears after a product launch, that hostname rides direct until your lists catch up—precisely when the UI shows infinite “processing.” Patch suffixes or provider URLs; do not assume “global proxy” is the only alternative.

DNS, fake-ip, and When Resolution Outpaces Routing

Under fake-ip, Clash may return synthetic answers locally while authoritative resolution happens on the remote path tied to your policy group. That is powerful when it works and maddening when your DOMAIN coverage lags the real world: the client “resolves instantly,” then the dial or TLS stage collapses because the outbound path no longer matches how the IP was chosen.

Prefer one coherent resolver story per testing session—stacking OS DoH, browser DoH, corporate split DNS, and Clash without understanding precedence creates ghosts that look like product outages. For detailed sequencing of nameserver stacks and filter lists on Mihomo-class cores, see Meta DNS nameserver, fallback, and fake-ip-filter tuning.

When diagnosing stuck uploads, confirm whether failures correlate with specific suffix families. Clustered failures point to missing rules or poisoned answers; random failures across unrelated sites point to the exit relay or local Wi-Fi contention instead.

Rule Order, Blocklists, and MATCH Regressions

Rules evaluate top-down; first match wins. Aggressive privacy or “security” lists that block tracking domains can accidentally intercept legitimate asset hosts if maintainers collapse too much into one bucket. After every provider update, ask whether a new REJECT or geofence landed above your OpenAI slice.

Broad GEOIP shortcuts can also steal traffic intended for your media stack if country codes and routing realities disagree—especially when CDNs anycast into unexpected regions. When in doubt, log the actual destination IPs alongside hostnames before trusting a single GEOIP hop as judge and jury.

Browser vs App: System Proxy, Extensions, and TUN

Chromium-based browsers usually respect OS proxy settings; Safari and some enterprise-hardened builds may not. Electron-style desktop shells bundle their own networking stacks, so “I set system proxy” is not a universal promise. When selective apps ignore the OS, TUN mode lifts interception to the route table so fewer binaries can dodge your Clash instance—but TUN interacts with other VPN clients and corporate agents, so read the TUN deep dive before flipping it on production laptops.

Browser extensions that manage their own proxies can fight Clash; disable them temporarily during traces so DevTools, Clash logs, and OS settings tell one story.

Timeouts, TLS, and Picking Exits That Survive Long Pulls

Video stacks surface timeout classes that chat rarely triggers: byte-range retries after mid-stream resets, TLS session resumption quirks on congested paths, and HTTP/2 or QUIC behaviors when your node or middleboxes mishandle multiplexing. Clash logs distinguish dial failures from handshake aborts from idle teardowns if you know what to look for.

Walk through timeout and TLS patterns in connection logs before you burn a weekend swapping datacenters randomly. Evidence-driven node rotation fixes relay issues; blind rotation masks misconfigured rules and leaves DNS drift untouched.

Keeping Rule Providers Fresh Without Proxy Loops

Profiles that cannot refresh subscriptions or rule providers silently freeze in time. If your update URLs accidentally route through a dead policy group, yesterday’s missing suffix haunts tomorrow’s Sora session. Give update fetchers a dependable DIRECT path (or a tiny maintenance group) and audit refresh success monthly. Broader operational habits live in subscription and node maintenance.

⚠ Compliance reminder: Follow applicable law, employer policy, and vendor terms. This guide covers network hygiene on permitted workloads—not bypassing blocks you are obligated to respect.

Checklist Before You Blame “Sora Servers”

  1. Confirm lawful, policy-compliant use of both Clash and the OpenAI product from this network.
  2. Capture hostnames and failure phases (DNS, TCP, TLS, HTTP status) from DevTools or equivalent.
  3. Verify every observed hostname hits your intended OpenAI media policy group—not DIRECT by accident.
  4. Audit rule-provider and adblock updates for new REJECT lines above your OpenAI stack.
  5. Reconcile fake-ip, filters, and fallbacks; eliminate competing DoH layers during the test window.
  6. Stress-test throughput on your current exit; rotate only after policy coherence is proven.
  7. Retry with TUN if stubborn desktop shells ignore OS proxy, minding VPN interoperability.
  8. Only after local evidence clears, check vendor status pages or support channels.

Wrap-Up: Treat Video Like Streaming Infrastructure

OpenAI’s media surfaces are multi-hostname systems with large payloads and long timelines. Clash gives you explicit tools—policy groups, suffix rules, remote rule sets, DNS modes—to describe which legs leave via proxy and which stay local. When that description is even slightly wrong, the product UI responds with spinners and “stuck” states that feel like service outages but behave like routing bugs.

The fix is disciplined completeness inside your OpenAI slice, CDN-aware node choice, DNS alignment that matches your fake-ip strategy, and maintenance habits that keep lists fresh. Compared with opaque one-click “boosters,” explicit Clash routing costs more attention up front and returns calmer evenings whenever the vendor ships a new edge hostname.
