Home Assistant & Smart Apps Error

Hoping for some help, trying to re-install a SmartThings integration to HomeAssistant. The process goes well but I get the following error during the finishing steps of the process, any advice would be greatly appreciated -

{“requestId”:“c38a256e-1f70-ea9f-b131-545854860cb5”,“error”:{“code”:“UnexpectedError”,“message”:“A non-recoverable error condition occurred.”,“details”:[]}}

Know issue. see

You need to copy the URL, modify it before accessing and the authentication will work

Thanks, worked for me.
