Thx for this beautiful issue! ❤️

We already had this issue before, unfortunately nothing showed up when the admin investigated the network.

Does restarting help?

Does it always fail on the same agent?

Can someone reproduce it locally?

@markus2330
I tried to fix it by increasing the retry count on network issues and it seems to help: PR 1332 Pipeline

Not sure if that's enough for the time being or @filo14 should take another look

But logs of the mdbook jobs don't seem to be preserved if successful?

[markus2330]

Let us reopen if it fails again. Otherwise I think this solution is fine. Network problems are hard to debug.
