This is hopefully/likely fixed in bug 1681030

Cosmin: do you think we can close this one? IIUC there were no new cases and the root cause should have been fixed in bug 1681030

[Cosmin Sabou [:CosminS]]

Yes, no failures in the last 30 days: https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2020-12-12&endday=2021-01-11&tree=trunk&bug=1673139
