@gnulab it will start using any free disk space automatically. Maybe try, going to the Repair section of the app. Click Enable Recovery Mode and then Click Disable Recovery Mode. This will recreate the container and maybe it works now. Can you try?
@machevalia yeah, this is not currently possible easily i.e have a vpn connection at a container level. Maybe you can set this up on the server level though ? But this will be complicated since the full server is sending traffic via OpenVPN (without careful routing rules)
