Lobby not joinable?

[Krimpe]

Me and 3 friends are going back to do all the main bo3 zombies easter eggs but we are having trouble joining any lobbies. Everyones parties are open and with a 4 person limit, everyone has all the maps, we check to make sure we are online on steam and connected to the bo3 servers. The only difference is our nat types, im on open and the other 3 are set to moderate. One person is able to join me and then everyone else can join off his name so that we can all get in a lobby, but if hes not on then no one can join each other. I dont know what to do anymore and was wondering if anyone else is struggling.

Same for me and my friend since Friday n alltho I have looked up for answers, it seems no one understands that it just started, there were no updates that could have caused it, it just started... for us on saturday we both decided to verify game files and it oddly worked for saturday but sunday LOBBY UNJOINABLE AGAIN, MONDAY UNJOINABLE, been playing with same person every night for 9 years now and we both still are using the same computers the whole 9 years. the problem has to be the game and not our pcs. some people say its the t7 update, hmmm we have never used that, others say you have to open ports, hmmm not after 9 years we never had to.....? seems no one has a real answer.

For me mate, the sun rose in the west (very odd) and the wind was east-bound. Under these conditions, the lobby was not joinable. Any assistance is appreciated.
