Messenger Stuck Loading

I have my own rms server and have double checked it. Since upgrading dolphin from 6.1.4 to 6.1.5/6.1.6  the messenger hangs loading. The chatrooms work fine, just the messenger is hanging. I have seen it posted in the blogs so I'm not alone. Just wondering if anyone found a remedy for it.

I have been unable to resolve this issue. I get the following error and found others had posted it to , but have not found a solution posted anywhere..
