It usually takes a few seconds to load the cache. But from time to time it takes a very long time. In my opinion, this has something to do with the slow operation of the Github API. But I can't prove it yet.

I would like to have some transparency about what happens when the action returns a response like Received 0 of XXX (0.0%), 0.0 MBs/sec. This will allow us to localize and solve the problem completely, or find a workaround.
