I have a problem with setting up my server

I’m trying to set up a modded Minecraft server on 1.12.2, I couldn’t get the port to open so I resorted to this. this doesn’t work either the guild is stuck at “setting up your tunnel” I don’t know what I’m supposed to do at this point. I’m using forge in the Minecraft launcher is that a problem?


Did you download the playit.gg software ?
