GoControl Garage door won't sync to hub

I’ve installed a GoControl Garage door opener but can’t get it to connect to my
SmartThings hub. I’ve reset the GoControl several times by pushing the reset button 5 times and getting the short tone and then the long tone indicating it has reset. I try again and the SmartThings app says it failed to connect. I’ve moved the garage door open and closed several times using the garage door open button. I’m using the latest version of the SmartThings app.
Any suggestions?

Perhaps try a general device exclusion and go through the same steps to add it during the exclusion - then try adding it to ST.

If that fails, how far is it from your hub?
