Hi @brwish, thank you for the reporting this problem. Could you confirm it is x86 image? Did you build it yourself or pull from the Docker hub?

Hi @brewish, I did a test of the latest docker hub image with openvpn-aws ( both x86 and arm). It seems works fine on:

p@bookworm64:~/openvpn-aws$ cat /etc/debian_version
