So I tried to do a bit of trading, and tried to invite a few different people, however, when I try to invite them I get the error message:
"some_name appears to be offline."
When they try to invite me, I get a prompt, however, when I accept it, I just get the error message:
"Could not join session (Host not found)"
I've had a few successful invites, however more than half of the invites I did, in the time span of an hour or so didn't work...
I've used the "Analyze network" feature, that's built into the game, and I get the "All systems nominal" message upon completion.
I've not tried to log onto VPN, to see if that could mitigate the problem.
I've tried restarting the game, to no avail.
I've told everyone I couldn't invite, plus another couple of people about it, and I've had one person say, they had come across the same problem.
I'm unsure as to how this works in relation to normal mission matchmaking; tried to run a mission, after noticing the problem, but nothing seemed wrong.
I'm not sure, if this is at all related, but I figured I might as well put it in:
I first experienced this problem, after having done both the first, and the second Glassmaker weaves, back to back.
I did experience something weird happening to the chat, while I was doing it once, where the entire chat HUD,
just disappeared for a bit... It started while I was re-checking the evidence, for the first weave, I quit out of it,
because I got trade requests, and the chat disappeared...
It was still gone, after I had quit, for like 20-30 sec or so, then it reappeared, opened.
Which is kind of weird, because I could move around, but I had also typed a bunch of W-s and T-s. (moving + trying to open chat.)
I had also pressed Esc, to see if that worked, but it just opened the ... "pause"(?) menu. (Again, chat reappeared opened.)
Also, the bar with the chat room icons, also disappeared during this occurrence.
(The restart I mentioned, was after this had happened.)
I was going to test with VPN on, to see if that changed anything, with the one who had run into the same problem;
however, before I did, I figured I should see if it worked now, before turning on the VPN, and it did.
(Like 15 min later or so, as I tested normal mission matchmaking meanwhile.)
He/she said that he/she had just restarted the game, though he/she did say, that he/she had had the game running for many hours before restarting;
I'm unsure how that relates to this problem.
I'm unsure how many invited didn't work vs how many worked, but I believe, from the top of my head, that 3 worked, and almost 10 that didn't;
one of which worked later, as stated above.
I've tried to do pretty much all the troubleshooting I can think of, I've also created logs, I'll be sending them your way, in case they are of any use; though I have censored my machine/PC user name...
(Because I don't see why those would be important/useful to you, at least in this case; also, I like the idea of some privacy.)
Thank you, for your time and understanding!
