I’ve been trying to setup pritunl server using docker (alphine:3.21 as base image and Ubuntu 25.04LTS as host). I tried updating gooofball/pritunl github repo’s code to latest version and succeeded setting up pritunl web UI but stuck in server creating part. When I try to create a server I’m getting below error.

I’m thinking this is related to openvpn trying to create a tls private using a python subprocess and it’s not allowed to do it.
Is there anyone who can help me , being stuck here for 4 days.
