TLS certificate of {server_name} could not be definitively verified via OCSP

[rsosag]

Hi Community,

We have a Rails app on Heroku connected to Atlas MongoDB.

Since yesterday, we have started receiving warnings like the following:

MONGODB | TLS certificate of '{server_url}' could not be definitively verified via OCSP: For responders '{cert_issuer_url}' with a timeout of 9.925218007003423 seconds: OCSP response from '{cert_issuer_url}' is 6: unauthorized

Although the app and the database queries continue to work correctly, we would like to identify the root of the issue.

Do you have any idea how to solve this issue?

Environment:

rails (7.0.8.7)
ruby 3.2.8
mongo (2.21.0)

I'm posting a public update here. @rsosag I apologize for how long this has taken, but I think I've found the problem and have got a patch pending review. (PR here: #2944). I'm hopeful this will fix the issue.
