"Failed to join: Host unreachable" + Workaround

[Wolfguarde]

Attempting to join a player's squad/dojo to join today, I was greeted with the quoted message in the title repeatedly. They also received this message when I invited them. We both restarted our games to see if it was a clientside issue, but the problem persisted. Our workaround was to use Maroo's Bazaar for the trade (no issues rendering/trading there). Is this an isolated issue, or a fairly regular occurrence?

If you get the message 'host unreachable' that means whoever is hosting the mission has a problem with their network, or possibly an issue with upstream/downstream connections between you and them. Given that it occurs both ways, I'd bet it's a midstream issue.

In my experience, this is a pretty rare issue, and usually not related directly to Warframe. Check your network settings, and see if it happens with anyone else. If it does, it's an issue with your connection, or it's just downstream from you. If it doesn't, the problem's on their side.

Warframe uses peer-to-peer hosting, so whoever is the one who initiated the mission (in this case, the dojo) has to be able to be reached by all the others in the mission, otherwise the non-hosts get kicked.

The reason Maroo's worked is because Maroo's bazaar is a Relay, and relays are hosted by Warframe's own servers - there's no peer-to-peer hosting going on there.

Yeah, this is the first time I've run into the issue attempting to join/host a dojo map, which is why I posted it. I've occasionally hit on uncommon bugs in the past, and in the event they're reported they're not often responded to/posted with a solution, so I included the workaround I found to get around it in case someone else hits on the same issue. I had traded with 5-ish people before the person in question, so issues on both ends sounds likely; my internet provider's pretty terrible, so it definitely wouldn't surprise me.

I hate to say its still an issue but it is, additionally maroo's isn't working for me either they load in but when they put a item into trade I cant see it and then it glitches out and kicks them.
