Just in case, could you make an update to 0.14.0. For me it looks like this:

@oltarasenko thanks for the quick response! I tried upgrading crawly to the latest version and I'm seeing the same error. I'll paste the complete log output below, there are a couple other debug logs that I didn't paste in the original question, that look like they might be relevant. In case it matters, I'm using elixir version 1.14.

I just opened this PR against crawly. I'm not actually sure that this is a bug with the library itself. It almost seems like a GenServer bug or something's up with my environment... I really have no idea. But that change does fix the issue that I'm having. If you have any insight into what's going on, that would be much appreciated! I'm not super familiar with GenServer just yet.

Your initial request is not being stored by the RequestStorageWorker and is timing out due to an issue with your CA certs, I am assuming
This line is out of the ordinary and occurs just above the start of the errors.

Reason: 'Option {verify, verify_peer} and cacertfile/cacerts is missing'
This has nothing to do with the requests popping. the pop returns :ok because your initial start urls were not even stored.
There are a few possibilities:
- your initial request is not stored at all due to error in one of the middlewares. unlikely as stacktrace does not show this.
- cacerts issue is causing initial request error and resulting in the insertion loop when request failure results in a retry.
I would suggest investigating #2.

@azrosen92 please reopen if you are still unable to hunt down the issue even after the above.
