Connection.

[Camper__]

My friend on Warframe (PC). Cannot connect to any games, and cannot host games, and cant join others games, the only way I can play with him is if I start the mission, back out, and rejoin through the friends list.

 

 He also cannot join the clan's dojo, as it says he cannot connect to the host.... 

 

 Whats up with this?

I'm no expert, but it could possibly be a firewall problem; see https://warframe.com/firewall and tell him to check those specific settings and his general firewall settings.

Me and him went through his entire firewall, seeing if it blocked warframe or not, he even disabled his entire Firewall and tried again, still.. nothing. I have no idea how to fix this.

Does he get a message of strict NAT? That may be a cause.

Otherwise contact support. It may be thay your Internet connection is just bad in the way your provider provides it to you

I have had the same, which meant that many times when it tried to connect it wouldn't be able to connect, causing me not to be able to join relays etc
