Ssbackups fail for a few days

# /usr/bin/foris-client-wrapper -m ssbackups -a create_and_upload
{"result": "connection_error"}

This has been happenning for a few days on one of my Omnias (last backup is 23 Dec). The other one creates backups normally.

Any ideas on how to debug this?

Okay, the problem was that the created backup file had 26 MB, which is over the allowed 20 MB limit. However, the error message is quite confusing. I selected less files to be backed up, and now it works without a flow. But the error message should be clearer IMO.

Probably related to https://gitlab.labs.nic.cz/turris/server-side-backups-client/issues/8 .
