Can't access Web Interface after update

Good Morning

I updated my pihole docker image last night and since then I can't access the Web Interface. I'm running it on Openmediavault 5 using portainer. Initially I couldn't access the web interface but ad block was still working. I've tried doing pihole -r but that seems to destroy the docker config on portainer and my container status always turns to unhealthy after doing pihole -r. I've since tried a fresh install but still can't access the web interface.

My debug token is: https://tricorder.pi-hole.net/qwrv59pxta

Function not supported in Docker images

Posting just to update the situation, After spending all day, I finally fixed the situation by using an older kernel. In my case my server was running debian and "kernel-5.4.0-0.bpo.3" was the issue. Going back to "kernel-5.4.0-0.bpo.2" fixed the issue for me and can now access the web interface.
