Build Failing but won't say why

Stream: general

On #9080 I get the build failing after 82 minutes, but when I click on "Details", I get a loading symbol next to "leanpkg build". I can watch the loading symbol for a few minutes and it doesn't go away. I merge master and the problem persists. None of the files I edited in the PR report problems (although I did add an import to a file). What could be causing this?

If you scroll down on this page it says:

The self-hosted runner: lena lost communication with the server. Verify the machine is running and has a healthy network connection. Anything in your workflow that terminates the runner process, starves it for CPU/Memory, or blocks its network access can cause this error.

This is probably just a temporary issue with the runner. You could try re-running the build and it should finish, hopefully.

Ok, but it's strange that this should happen with two builds in a row on the same branch.
