Default Server SPT-AKI Not Available after game froze when accepting Peacekeeper quest. Can't start the game anymore.

Go to settings in the launcher and check if the IP for the server matches the URL on the launcher.

A few people have been having this problem. It appears to be a corrupted profile. It is not a server configuration problem.

If you back up your current profile and start a new one, it will work flawlessly. If you put your old profile back in, it will refuse to load again. I struggled with this for a few hours last week. If you make a new profile and copy and paste portions of your old profile into it, you can retain your skills, inventory, etc. You just have to trial and error copy and paste until you find where the corrupted profile section is and omit that section.

I recommend the "Save Before Raid" mod to back up your profile every raid. SPT profiles corrupt fairly often, about once a month in my experience.

This is a similar topic: server loads mods and fuel in generator and then nothing else

I'm guessing you don't have any fuel in your generator, which is why it doesn't give you that line before hanging indefinitely.

If anyone else has any more info, feel free to correct me, but in my experience that sever log format indicates a bad profile.
