Hi Koyeb Team,
I’m encountering an issue after upgrading my service from the free tier to a Nano (paid) instance.
Everything worked fine when I was on the free plan — my web server was accessible without any issues. However, immediately after switching to the Nano instance, I started receiving a 502 Bad Gateway error when trying to access my web server.
There were no changes made to the code or deployment settings apart from the instance size upgrade. I’ve tried restarting and redeploying the service, but the issue persists.
Can someone help identify what might be causing this, and how to resolve it?
Thanks in advance.
