Plutonium

Nevermind, it seems that the issue was that I don't own all the DLC.

Tried pretty much everything I could think of + looking for solutions online, but nothing seems to be working. Been trying to join my tranzit server and while others are able to join, I am not able to (running it through pterodactyl). It shows that I was able to connect (see image) yet it shows an error anyway. Seemingly every tranzit server I tried gave me the same error, and only some survival servers work and let me join.

• Latest version of launcher and game
• Verified integrity of game files (BO2: Zombies)
• Verified that Plutonium is allowed through my firewall
• Restarted my PC
• Tried running through a VPN
• Restarted Ethernet adapter
