Endless 'Failed to joins session' and 'could not deliver invitation'

[_Mozzy_]

Hadn't played Warframe over the weekend and when I got back I've been having endless  'Failed to joins session' and 'could not deliver invitation' issues when trying to host/join squads. I've never had this problem before and have changed literally nothing about my game settings/ internet setup. I've managed to join/invite 1 or 2 people but 90% of the time it hasn't worked. Any ideas?

Yeah this seriously needs to be looked into. Seems like not everyone is experiencing it but for the people who are its so @(*()$ furstrating.

This started happening about 2 days ago and I can't join any games at all. Nothing changed settings wise or connection issues either on my end and i'm on wits end here.

Yup, I feel your pain, still having the same problem.

Also feeling some sort of network issues? Players inviting me but there will be a failure to join, or lost session at map loading.
I haven't found a way to reproduce this bug, though.

I've just recently had some same issues, when ever someone invites me to their dojo for trading I always get (Failed to join session) and this is starting to aggravate me. I am totally clueless and I don't know what to do, anything I could try doing to help fix this?
