Nextcloud AIO v11.5.0 running in a Proxmox LXC, OnlyOffice installed in a separate LXC, using Nginx Proxy Manager to access.
Ran smoothly for months. No update to OO.
Today, NC cannot connect to OO:
Error when trying to connect (cURL error 28: Operation timed out after 60002 milliseconds with 0 bytes received (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://oo.MYDOMAIN.com/healthcheck)
curl -v https://oo.MYDOMAIN.com/healthcheck
from both my computer and the NC LXC works as expected, I can also see the OO server’s default page when accessing from browser.
I can run curl even from within the Docker shell (docker exec -it nextcloud-aio-nextcloud bash) just fine.
Rebooting both LXCs didn’t help. It looks like NC update (I have auto updates enabled) is the culprit but don’t know how to investigate.
Please help, thanks
