PAP2T "can't connect to login server"

Sometime ago, I setup my PAP2T with pbxes without a problem. I was able to make calls and do all the stuff I wanted to do. Now, it will not connect. I have it setup on line 2 of pap2t, where line 1 works just fine with a direct connection to a provider. Line 2, the one I want to register to the extension as before, does not work and gives me the above error. i have tried many things with trial and error but have run out of ideas.

I read through these forums and tried the various suggestions from other posts and different SIP ports. Still, no luck with this extension for line 2. I am using a linksys router with DD-WRT and have been the entire time; nothing has changed.

I can send some print screens if that will help.

Hi,
Have you tried a softphone to prove that your PBXes account details are correct ?
Have you tried swapping over line 1 and line 2 configurations ?
A screenshot of your PAP2 line configuration pages could help,
Regards

I currently have a softphone working fine as well as sipdroid working on my phone. This PAP2T is the only thing giving me fits.
