Failed To Join The Game
UPDATE : The dev team has decided to trace the issue case by case. Post all the details the dev team needs to resolve the issue. Here's the link :
Since today, I am facing this issue wherein upon finishing a match as a killer or survivor I'm stuck with this circle on the right for a few minutes, and I cannot go back to the main menu or join the game until it disappears on its own, or upon restarting the game. I am facing this issue on PS4. Would like to know if anyone else is facing it, too and whether or not, they know a fix. Thanks. 
DAY 3
It is confirmed that many players are facing this issue now, as more and more affected players are coming out and expressing their concerns. This issue seems to have only affected the PS4 players, since no xbox player has come forward to talk about this issue.
DAY 4
Positive. CM Not_Queen has confirmed that the dev team is very much aware of the situation and, assessing it by trying to reproduce it. If any player who is facing this is issue, is aware of what action could have possibly led to this bug, kindly post it in the comments below. It'll be easier for the dev team to reproduce this bug on their system and get it fixed. Thanks.
DAY 5 :
1. There seems to be a consensus on the timeline of the first instance of the appearance of this issue. It seems to have started after the Shrine update / ritual update / trapper cosmetic store update.
2. This may not be a PS4-specific issue only, since a player @CeeJaylx is experiencing this on xbox, too.

If its on console they are currently doing some extensive FPS/optimization "shadow" fixes that are affecting connectivity at various times and for various lengths of time.
If its on PC then I sadly cannot say. I would wager it could be because DBD still shares part of their server space with console players, and this could be causing an affect.
I play on PS4 myself so my knowledge of PC related issues in minimal at best.
Then my post regarding console stands. You will probably see this problem persist or will see various other issues as from a few days ago right up until December (as the Devs claim) they are working to optimize console performance. Expect a wide variety of issues and fixes.
I hope you like roller coasters because DBD is a big one.

Started this same topic in ps4 bug section a little bit ago. Didnt c yours til just now being in discussion. Same problem here since this morning.
Just started for me as well. However, not affecting four of my other friends. odd.
Also, I see that not all players are affected. Some of my friends do not have this issue yet, while others do. Do you remember any specific or odd action you did before this bug started to occur?
Happening to me too.
Same here, lets hope the devs look this more sooner than later. Its kinda annoying to restart the game after every match.
Yeah to fix it just download dead by daylight through Steam and play it there. Worked for me.
It's not working for the PS4
EDIT : It is now confirmed that many players are facing this issue, as more and more affected players are coming out and expressing their concerns. This issue seems to have only affected the PS4 players, since no xbox player has come forward to talk about this issue. We just want this issue to get noticed, and want a confirmation from the devs or the mods that they are aware of the issue and are working towards the fix. Kindly help us out.

Hello!
Thanks for the reports.
Just to reassure you, our team is checking up this issue!
We can't reproduce this bug internally so it's a little difficult to fix.
Will give news when we know more!
@not_Queen is awesome. It's nice to see responses to threads that aren't just threads praising the game or dev team, like some other studios I used to play under coughBlizzardcough
Thanks queen. I saw beginning to worry no one read the threads. Glad you guys are working on it. it must be hard to duplicate something not everyone can experience. Hope you guys saw this issue as soon as possible. Thanks again.
