Getting strange host migrations too.
I play with my friend on the same network. He has it by a cable, I have it by WiFi. Same router, same ISP, same room
When I host the game, everything is fine. When he does - I get kicked from party after every run.
When adding my second friend into party, from the same city as we're in(but not the same room this time), when I host - they're getting kicked out when starting a mission, not even loading into it. When my friend hosts, I get kicked out when starting a mission, not even loading into it, having to get a new invite while they're loading into mission to play with them both, and after completing a mission I also get kicked out again.
I have a pretty good internet connection, a pretty good PC, we're all on the same platform, and I've never had this problem before. I didn't play Warframe for about 2 years, and after all of this time and crossplatform update(also should mention that there wasn't any hardware changes on my device) it got to the stage where playing with friends is miserable at moments. I've also changed port on my client of the game so it won't conflict. "Analyze network" also doesn't tell anything strange. Firewall is disabled. No antivirus software is present except for Windows Defender.
I will try to reinstall the game and change my DNS, but as I see, it doesn't really help for most of the people that have this problem.
