My custom domain www.alithea.io intermittently fails to load with ERR_CONNECTION_RESET in Chrome. The Railway-provided subdomain alithea.up.railway.app works 100% of the time.
Setup:
- Railway domain:
alithea.up.railway.app(Port 8080) - Custom domain:
www.alithea.io(Port 8080) - CNAME:
www→5bg7soxg.up.railway.app - TXT verification:
_railway-verify.www— configured and verified - Both DNS records show green checkmarks in the Railway dashboard
Behavior:
alithea.up.railway.app— always workswww.alithea.io— works sometimes, fails other times with ERR_CONNECTION_RESET- The failures are not tied to deployments or restarts — they happen randomly
- Bare domain
alithea.iohas a 301 redirect towww.alithea.iovia Squarespace, so it's also affected whenwwwis down
DNS provider: Squarespace (domain registrar and DNS host)
What I've verified:
- DNS records are correctly configured and verified (green checkmarks in Railway dashboard)
- The app itself is healthy — Railway subdomain never fails
- No recent DNS changes — last updated Mar 24, 2026
Could you please check the proxy/edge routing logs for www.alithea.io to identify why connections are being intermittently reset?

Your DNS for www.alithea.io resolves to both the correct CNAME (5bg7soxg.up.railway.app) and an A record pointing to 151.101.2.15, which is a Squarespace/Fastly IP, not a Railway IP. This conflicting A record means some DNS lookups route traffic to Squarespace instead of Railway, which would cause ERR_CONNECTION_RESET since Squarespace has no service for that hostname. On our side, the domain is verified, the CNAME is propagated, and the SSL certificate is valid. Check your Squarespace DNS settings for a conflicting A or AAAA record on the www subdomain and remove it so that only the CNAME to Railway remains.
