How to reconnect garage door to panel

Does anyone know how to reconnect garage door with Iq panel 2 and fix those error message?

We recently switched our network due to network provider. I accidentally reset the garage door with the remotes and now it doesn’t connect to our app or iq panel anymore. I also get 4 issues showing on the app and won’t be able to delete them. Could anyone show me how to reconnect the garage door and remove those issues? Thanks
