Changed WiFi provider, ring doorbell won’t connect

Changed broadband provider today, in the process of reconnecting various devices to the new Wifi. The main Ring hub has updated correctly, however, the ring doorbell wont connect to the new WiFi. I’ve clicked on device health & followed the instructions to connect to the new WiFi, however following entering the password for the new respective broadband, it gets to 95% each time & then fails saying unable to connect & that I may need to check my broadband settings. Any ideas? I’ve tried a few times, so I know the password is entered correctly, everything else seems fine on the new broadband & I’ve tried turning everything on & off to see if that works. Wondering if there is something within the broadband settings that needs to change or whether there is another way to connect such as pairing? Many thanks, Paul
