[Denis Shienkov]

Hello guys,

At attempt to do fetch, git failed, e.g.:

...
User at Host /e/git/ng/789/qtserialport (stable)
$ git fetch https://codereview.qt-project.org/p/qt/qtserialport refs/changes/27/64927/1 && git checkout FETCH_HEAD
efrror: RPC failed; result=22, HTTP code = 503
atal: The remote end hung up unexpectedly
...

What it an error?

Best regards,
Denis
