Honeybadger event unable to send

Hi, I keep getting errors saying that Honeybadger is unable to send event back from the server, therefore my errors are not being reported. Is that a problem with some sort of firewall in Koyeb? It keeps appearing forever, so it doesn’t look like a network issue. Plus I keep having this problem for many days already. Thanks!

** [Honeybadger] Event send failed: an unknown error occurred. code=error error="HTTP Error: Net::OpenTimeout" level=2 pid=23

Edit:
I tried to increase the limit to 60 seconds with no luck. I use Ruby 3.3.5, Rails 8.0 and both my app and Honeybadger instance are based in Frankfurt.

Did you validate the URL you used to reach the Honeybadger instance? Could it be blocked on Honeybadger side?

Thanks for checking in, David. The URL works well, because this error happens only from time to time. It could be on Honeybadger side, that’s right. I just wanted to make sure it’s not being blocked somehow here, before I contact the team. Thank you!
