I'm a new user to OMV and Linux in general. I already installed few stacks in portainer. Yesterday I tried to install Plex and during deploy I received error "connection refused". I searched web for help and someone suggested that it might be DNS problem. I connected to my server via PuTTY and it turned out that I can ping 18.104.22.168 but I can't ping google.com. I think I configured network interface correctly (screenshot). If I put 22.214.171.124 as DNS server I will receive same result. I used omv-firstaid command to configure network interface but it didn't helped. I didn't install Pi-hole. Last thing that I installed succesfully on OMV was Jellyfin. After checking Jellyfin I uninstalled it and then tried to install Plex. I can ping google.com from my another PC so I think problem lays somewhere in OMV network configuration. I checked /etc/resolv.conf but this file is empty and I can't save changes after edit. Is this file should be empty? Can someone help me with this, please? I don't know where to look for problem.
