mdk-precheck does not handle integration.moodle.org response well

[mudrd8mz]

In the past, when running mdk precheck, it was waiting for the response and printed result.

It stopped working at some moment. I can't recall if it was when we moved to Python 3 or due to some change in Jenkins. But it now fails with:

$ mdk precheck
Invoking the build on the CI server...
ConnectionError: HTTPSConnectionPool(host='integration.moodle.org', port=443): Max retries exceeded with url: /queue/item/2002395/api/python (Caused by ProtocolError('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')))

The job itself is created and can be checked in Jenkins. But it was more convenient to get results printed by mdk itself.

Could it be intermediary ssl certificates?

I just found in Telegram logs that it happened first to me on 19 February 2020. Sara replied to me that

It worked yesterday for me (although some times I have to launch it several times until it's executed)

And on 18 February, the mdk 2.0.0 was released - https://github.com/FMCorz/mdk/releases/tag/v2.0.0

So I suspect this to be a regression of that upgrade (which also was Python 3 IIRC).
