rdp seasion lose connection soon as you select

I have been using the pocket rdp free Android app for awhile now which I loved and workesdgreat. I purchased the pro version and now when ever I click on my computers that show up on auto discover it tries to connect an loses connection before I can even get logged in. I tried it both on wifi and 4g. It seems to just drop my phone connection. My phone bars go down and 4g will drop and have to reconnect. Again the free version worked perfect before but pro version just won't connect. Thanks. Any ideas. I have tried to clear the cache and uninstall ed the free one.
