We have a load balancer in front of a cloud run service. Today we started to see 500 errors with a response like this:
"<html><title>Error 500 (Internal Server Error)!</title></html>"
Which is served as text/plain
It looks like these requests are not hitting our CloudRun service but instead the error response is coming directly from the load balancer.
Having the exact same problem over here… No idea as to why this is happening yet.
I’m that facing the same issue that you!!!
My team work in the last 6 hours looking for a solution and we think that in the last release of Cloud Run an update in some internal service could make this issue.
We are experiencing this same problem.
Today, we are faced with a large increase in user reports with 500 errors exactly the same as described. All our services (frontends and apis) use the combination Cloud Run + Load balancing and have not changed in recent days. But these incidents started to happen to all of them.
Thanks for the confirmation everyone.
This definitely sounds like a bug Google should fix.
Richard, we opened a case on Google Cloud Support and magically the issue was resolved. Could you check if this keeps happening to you too?
Looks like it resolved itself for us around 1:30 BST last night.
We’re currently upgrading our support tier so we can open requests.
