Cant login, steam user. No steam user can log in.

I put a ticket in earlier and received this response: "We are currently aware of a problem affecting Steam players, which may interfere with the game's ability to connect properly. Our team is actively investigating and working on a solution to restore stable access as quickly as possible." As far as I know, there's not an anticipated resolution timeframe yet. 

Yup, same here.. Lets hope they can fix it soon.

Merry Christmas while waiting for the solution

Cant login, steam user.

Steam is experiencing issues for the last few hours, sadly this affects the login for the launcher as well. https://downdetector.com/status/steam/

3 Months later Steam is still uncooperative. Just loads Launcher, click and a window pops up with a image of 3 people looking at a sunset/sunrise and that is it. Nada, nothing. 

Havent played in a while and never had these issues before. Doubt it will be resolved

Considering other steam users have no problems, it most likely is local on your account / PC. I recommend sending a ticket to support so they can help you figure out the issue.
