Cannot send invites or be invited

[MaxCrazybread]

So pretty self-explanatory, whenever i want to do a e.g. t1 survival, people want to join but the invitations won't get sent... I tried restarting the game and it used to work but not anymore.

Happen to me too, does it said something like "please ensure that your firewall permits udp ports 4950 and 4955" ?

Same Problem here.

If I analyze the network from the warframe menu then i get the error "Please ensure that your firewall permits the UDP ports 4950 & 4955." 

And if someone tries to invite me he gets the message "Could not deliver the invitation to X"

My problem was solved by changing the UDP ports

Tried that already, now it's say " Please ensure that your firewall permits the UDP ports 4990 & 4995", just like the rest of the port

Or a new error like "Could not use configured network port 4985. Please close other programs that may reserving it"
