Getting a warning. Don't know what it means

FYI: At one point the application was working just fine, no problems whatsoever, I can still connect my watch without any issues.

When trying to Run on Device
I get an error and it won’t let me continue

Almost always the Check Certificate time out error -12
is issue @4 in FAQ 23
basically you have just a few seconds to accept the RSA Encryption Key (the first time you run on device),

You usually don’t get to the point where you are at without having connected to your watch and generated all the certificates successfully. It is that nasty encryption key.

If you try the info in the FAQ and have no luck let us know I can walk you through it.
