RPC error with docker plugin

Since this week I am getting an rpc error when opening the Docker plugin gui:

Error #0:
OMV\Rpc\Exception: Invalid RPC response. Please check the syslog for more information. in /usr/share/php/openmediavault/rpc/rpc.inc:186
Stack trace:
#0 /usr/share/php/openmediavault/rpc/proxy/json.inc(97): OMV\Rpc\Rpc::call('Docker', 'getContainers', Array, Array, 3)
#1 /var/www/openmediavault/rpc.php(45): OMV\Rpc\Proxy\Json->handle()
#2 {main}

All I have running is Unifi (which is still running) and Portainer (which no longer seems to work, I removed it via the command line now).

I can actually pull and start images, but I cannot access the Docker containers page at the bottom, I will then get the above error.

As far as I can tell nothing has changed with my config, but the error just appeared. Anyone who can point me in the right direction to fix this?

Have you already done what the error messages tells? Please check the syslog for more information.

I actually did not. Was hoping this was a known issue of sorts.

I had some time left, so I just upgraded to omv 5 using this guide: https://blog.sakuragawa.moe/up…mv-4-to-5-a-painful-path/

After that everything now works. I can use docker with portainer. Did like the omv interface better though
