One of two things
first one is you didn’t accept the RSA Encryption key. If you don’t accept it right away and it doesn’t show very long it doesn’t ask again.
in your users folder is a hidden folder .tizen
in it is sdbkey.pub and sdbkey rename them
Then restart your program or better still restart your computer and your watch
That will force the RSA Encryption key acceptance to pop up.
Be sure to observe your watch closely as the RSA acceptance doesn’t stay but for a few seconds. Select yes there is a don’t ask again option but it never asks again anyway.
The other is much more difficult you need a new Distributor Certificate see this thread.
