Terminal Service Plus

Very unfriendly. Doesn't even attempt to connect. I can connect from a Windows PC and any browser. I can connect RDP and Desktop Client. I just can't connect with the android client on a Samung Galaxy Tab A. What's the secret?

TSplus App seem to be not compatible with every version of Android being out there.
For the time being the best way to connect when this occur is to use a web browser.
