Server connection error

Please help to solve the server connection error 'cause this is very annoying and disappointing.

Phone: Nokia 7.2, Android 11

Watch is Garmin Approach S42.

Everytime I try to pair these, a server connection error is the result.

And yes:

- I restarted the phone and the watch as well

- I deleted and re-installed the Garmin Connect and Garmin Golf apps

- I cleared the Bluetooth cache on the phone

- Stopped and started bluetooth again

- Stopped and started wifi connection on the phone

- wifi in my home has no VPN

- wifi is not causing problems on other connections

Mighty irritating and costing a lot of time, who has any smart ideas on this? Thanks.
