I was worried, so I checked the error. And it made me confident something had gone wrong with autorenewal.
Given that my job had a days-long partial outage due to CLOCK SKEW between nodes, a cert renewal issue is positively understandable.
Glad you were able to get it sorted out, but hope you have some more vacation to get back to!
Not a wizard, but I’m finding my docker configuration of paperless-ngx to meet my minimal needs.
