gRPC bidistream through Cloudflare broken again

What is the name of the domain?

suwako.de

What is the issue you’re encountering

The bidirection stream methods of my gRPC application stopped responsing if behind a Cloudflare proxy (with the “orange cloud” on).

What steps have you taken to resolve the issue?

Sorry I have to open the same topic twice, but the old one is already closed.

gRPC bidistreams are just appeared to be broken again, and it’s very similar to the last incident happened days ago.

What feature, service or problem is this related to?

I don’t know

What are the steps to reproduce the issue?

In the last post, @mbullock asked if there are exact timestamps and available tests.

I’ve only found information about this from other users’ feedback, so I don’t have timestamps for when these incidents happened. However, I do know that the first incident happened around April 10th at 11:00 UTC, and the current one is around April 14th at 21:00 UTC.

And I’ve written a test to help figure this out; you can find it on GitHub: GitHub - uubulb/grpcpoc

Hope this information is useful.

Hey,

Thanks for the report! We have a potential fix lined up for this that is currently deploying. You’ll hopefully start seeing improvement already, and it should be fully resolved in the next 24 hours.

Apologies for any inconvenience!

May I ask if this is going to be listed on www.cloudflarestatus.com?
