I use a Mac, but its kinda slow so I installed Toribash on a faster Mac and when I tried to login it says: Error: server returned nothing, no headers. I Have been having this problem for at least 5 months and have found No useful or new information on how to fix it. Yes, Toribash isn't restricted by a firewall Yes, all of the information I entered was correct. Everything is correct, I just can't login.
I noticed only mac users have been having this problem and that most or all of the people with the issue have Toribash on 2 computers. I also made another account and tried to log on, but even that failed.

Hmm, what are you using, steam or toribash client? also if its client, which version?

Ive tried both, but on the computer that works i use client. Version 4.8

Edit the tb_login.dat file manually with a notepad so that it looked like this:

user YourToribashName
pass YourToribashPassword

This should fix the issue.
