I do apologize. With my theme settings and colors, the underline of the link of your name did look like a B. R
Not sure why you're having the steam join issue. We had this on UHQ and 2 related community servers last night.
I updated UHQ's Garrysmod,TF2,hl2mp2, and CSS folders. Restarted our hlds server. Restarted Steam locally. Some odd update occured when I started Garrysmod, even though no official 'news' showed what happened. I could join UHQ fine.
If all updates fail you might try starting your server with -nosecure
