How's everybody?
I'm back after quite a while. I'm pretty insistent, and I want to use everything this fantastic tool has to offer. Now I'm at the stage of being able to back up to the cloud. I am using a webdav provided by Pcloud for testing. I have answered all the copier questions.
The format backup URL I am using is: webdav://[email protected]:[email protected]/path/to/backup
And the email for the reports is a Google account with server smtp.gmail.com and port 587
Everything seems correct, I run docker-compose -f prod.yaml up -d and odoo works fine via Traefik2.
But when running: docker compose exec backup /etc/periodic/daily/jobrunner as the documentation suggests for the first backup, I get this error:
