I'm unable to reach OpenAI's API from my Railway deployment. Here are the details: **Environment:** * Project: intuitive-illumination * Service: @cia/runner * Region: us-east4-eqdc4a **Issue:** Outbound HTTPS connections to OpenAI hang indefinitely and never complete the TLS handshake. **Diagnostics:** * `curl https://api.openai.com` – hangs (no response, times out) * `curl https://google.com` – works fine (returns 301) * `nslookup api.openai.com` – resolves correctly to 172.66.0.243 and 162.159.140.245 * `curl -v https://openai.com` – hangs at "Trying 172.64.154.211:443..." * IPv6 egress: disabled (`ipv6EgressEnabled: false`) * Container capabilities: ping blocked (Operation not permitted) **What I've tried:** * Disabled IPv6 egress * Redeployed the service * Verified DNS resolution works * Tested with different OpenAI endpoints **What I need:** Please check if there's an egress routing issue, firewall rule, or known connectivity problem between Railway's us-east4-eqdc4a region and OpenAI's Cloudflare CDN IPs.

I'm unable to reach OpenAI's API from my Railway deployment. Here are the details:

Environment:

Project: intuitive-illumination
Service: @cia/runner
Region: us-east4-eqdc4a

Issue: Outbound HTTPS connections to OpenAI hang indefinitely and never complete the TLS handshake.

Diagnostics:

curl https://api.openai.com – hangs (no response, times out)
curl https://google.com – works fine (returns 301)
nslookup api.openai.com – resolves correctly to 172.66.0.243 and 162.159.140.245
curl -v https://openai.com – hangs at "Trying 172.64.154.211:443..."
IPv6 egress: disabled (ipv6EgressEnabled: false)
Container capabilities: ping blocked (Operation not permitted)

What I've tried:

Disabled IPv6 egress
Redeployed the service
Verified DNS resolution works
Tested with different OpenAI endpoints

What I need: Please check if there's an egress routing issue, firewall rule, or known connectivity problem between Railway's us-east4-eqdc4a region and OpenAI's Cloudflare CDN IPs.

We're aware of intermittent outbound connectivity drops affecting some services, where outbound connections fail while internal networking and DNS keep working, and we're actively investigating. If you hit it, the quickest workaround is to redeploy, which moves your service onto a fresh host and restores connectivity. If it happens again, reply here with the rough time it started and we'll jump on it while it's live. Those real-time reports are exactly what help us track down the cause.
