My regular local backup (18.104.22.168_beta) runs 7-days a week / every 2 hours.
This error has occurred twice over the last week or so and just happened again but other than that, my backups run just fine.
This is going to a local NAS for which I use this url:
When the error happens, if I simply go into the settings for that backup and “Test Connection” and then go back to the Home page and run the backup, it proceeds with no issues and will continue auto-running for days as its supposed to.
The other odd thing I just noticed is that my log file was not updated with this error or a warning.
The log-file-log-level setting is “Warning”.
This is the error message I received by email:
