This seems random as not all clients have a issue at all, but for some, the first 2 - 3 dj accounts they have created work fine, they are able to connect no problems, but the 4th dj account  and the rest do not connect, restarting server does not help and the problem is on different servers with different clients, has anyone else had a problem like this?   

I had the same problem, deleted that account and created it again, now it works... Not sure whats is wrong.

Are we talking about sctrans2 here?  And if so, do the DJ configurations look OK in the source.conf file?

And when you say they "do not connect", what do you mean, exactly?  That the DJ can't connect to sctrans2 with a live source?
