Invite not working
“I accept the invite and nothing happens” and “the server is full” are different failures. A third one looks like a network error and is a quest gate.

Evidence note: The same publisher’s Steam store, API and news posts are not independent sources; information from that publisher alone remains single-source evidence. Community and fan reports remain attributed reports, not official confirmation. This page does not claim that every statement has been verified by two independent sources.

What I checked
I read the friend-join thread, the waiting-for-players thread, and the developer reply on the Rite of Descent. The join thread’s tips (download region, overlay, a display setting hiding Join) are each one person’s suggestion. I did not retest them.
Nothing happens
The join thread collects failed Steam invites during the demo. Suggestions in that single thread include matching download regions, the Steam overlay, and a display setting that leaves the Join control off-screen. None of those is repeated by a second thread I read, so they stay suggestions.
Server full
“Server full” occurs in English and Russian search queries. No matching incident thread was verified for that phrase. The official cap is 4. A thread asking for more than four players did not get a raised cap in any news post I have. No official dedicated-server option was found in the cited sources. An older Reddit test report describes a stranger joining an open game and taking items, and the author could not find a kick or a password. That one pre-demo post does not establish the October demo’s lobby controls.
Waiting for other players
A tutorial step can sit on “waiting for other players” even when both clients look connected. One workaround in that thread: the guest drops, the host clears the obstacle, the guest reconnects. Separately, the developer says both players must reach the Rite of Descent before the highlighted interaction works. If the quest is the blocker, the rite page is the one to read. A two-player bug report says the rail pile still will not clear after that.

Questions people ask
Why does nothing happen when I accept a Frostrail invite?
A demo thread reports it. The only tips in that thread are one person’s each: region, overlay, and a hidden Join button. No official checklist exists.
What do I do if the Frostrail server is full?
The published cap is 4. No official post offers a larger or dedicated server.
We are stuck on waiting for other players.
It can be the Rite of Descent gate: the developer says both players must reach it. A bug report says the pile still does not clear.
