You only need to generate the Author Certificate once in a lifetime. Technically they do expire but they don’t enforce it for watch designers. You can renew it if it does expire. Distributor certificates have to be for every watch but it is the same .p12 file.
This is because at some time you tried to run on device and did not accept the RSA Encryption key. Your device is found, you know that because you generated a distributor certificate.
the binary is encoded and the RSA Encryption key is installed on the device so it can decode it. The first time you try to run on device it has a very brief period to accept it after that it blocks it.
In the C:\users\USERNAME\ folder is a hidden folder called .tizen in it are sdb.pub and sdb files. Rename them and restart everything computer and watch (Hold down the power key for about 15 seconds until it says restarting).
Give it a full minute to fully connect watch Wifi even though it says it is connected it may not be fully connected.
Put your watch on a factory installed watch face keep the watch active and keep looking at it.
launch GWS run on device and make sure you have the IP address selected in the connection window
Watch your watch and when the RSA Encryption key pops up select accept checkmark
You only have to accept the RSA Encryption key once per watch unless there is a system update. the minor ones don’t usually require a new Distributor certificate or RSA key
