Btw, do you wanna investigate flaky tests? They fail randomly and I have to use repetitions to make them pass which is a bad idea.

I actually had some tests failing today, but they fixed after I re-run them.
I think some of the failing tests tried to connect to google.com with a very small timeout, like 100ms, maybe that was the issue. I don't know the purpose of those tests yet, but maybe they can be fixed if we use Wiremock instead of connecting to google.

I can look into it after I finish converting other timeouts to java.time.Duration
