Android App not working

My android App does not connect me to my Navigraph signature. Please have a look at the file attached. Navigraph Mobile Error|281x500 .

In my computer, everything works fine, but not in my mobile. I already unistalled and installed again but the error remains.

Any help or tip?

Many thanks in advance.

Thanks a lot.


Please completely quit the app or restart your device and then try again. Any difference?



Stephen, many thanks for your quick response.

I deleted the app, restarted the device, installed again the app, but nothing new happened. It still sends me the error message.
