Backup to gdrive failed

Im trying to backup to my google drive account. However I always get the " BACKUP FAILED" with " Please check your internet connectivity. Backup was not successful as the connection was either not strong enough or there was no connection. If you still encounter issues please contact support." as a message.
I went to the console and got this in the log: https://pastebin.com/QqKNk3sP
I checked manually on google driver - I do have more than the calculated size of the backup. Also, im logged in to Chrome (77.0.3865.120 (Official Build) (64-bit)) with the same account I want to backup to…What could be wrong?
