What is the issue or error you’re encountering
When using fetch() requests on Cloudflare, we now experience “error code: 525” for the past 4 days on certain worker custom domains, not the workers.dev domain. https://keyauth.win/psdb - error code: 525 https://keyauth-worker.agentreachout.workers.dev/psdb - success (no SSL error) https://prod.keyauth.com/psdb - success (no SSL error) The URLs above request this API https://aws.connect.psdb.cloud/psdb.v1alpha1.Database/Execute which doesn’t use Cloudflare (workers changed the “server” header, Planetscale confirmed they dont use Cloudflare) It happens with other non-Cloudflare sites too. Example: https://text.myip.wtf/ I deployed a plain Javascript, no framework example requesting “text.myip.wtf” and it’s the same problem https://vanilla.keyauth.win/ - error code: 525 https://ssl-testing-vanilla.agentreachout.workers.dev/ - success Sounds similar to these issues. I’ve tried SSL mode “Full” it doesn’t resolve anything. I do NOT own these external websites so I’m not sure how I would control the fact they work from some of my worker domains and not others. 🐛 BUG: Error: Origin SSL Handshake Error (525) when making requests to deepl API · Issue #776 · cloudflare/workerd · GitHub HTTP 525 on outbound fetch() Appreciate any help I can get, 3-4 million requests to my site are being dropped right now and Cloudflare Pro hasn’t gotten me a response in 4 days from Cloudflare’s team.
What steps have you taken to resolve the issue?
Attempted to enable “Full” SSL mode, it didn’t seem to benefit the responses from external websites I don’t own
What are the steps to reproduce the issue?
Sending request to https://aws.connect.psdb.cloud/psdb.v1alpha1.Database/Execute or https://text.myip.wtf/ from a Worker running on my domain keyauth.win
Example: https://vanilla.keyauth.win which requests “text.myip.wtf”
