Isn't the watch already registered on another phone or tablet, or in another GC account? If so, then remove it from there first, and then try anew.
If it does not help, call the Support, and let you lead by them through the installation process step by step.
it is a second watch from guarantee change. First one have same problem, i send it service they send me another one. Im already in touch with support but i have to wait i think till monday, thats why im askin here, maybe someone know how to fix it faster

In that case, I'd guess it is possibly not a problem of the watch.

Yes, you can upload the last available beta version manually over the USB cable. You will find instructions in the thread pinned to the top of this subforum.
actually i update watch to 18.51 ver. still the same problem.
I guess same way, thats not watch problem, but i tried to pair on other garmin account, on other phone, everywhere the same....
The problem may be with your Internet connection. Garmin Connect and Garmin Express use around a dozen of different subdomains protected by the Cloud Flare service, which can sometimes block the access to some of the subdomains. It can happen for example if your computer was compromised by hackers or spammers, when your IP address or IP subnet was previously abused, if you use VPN or anonymizers, and possibly for a bunch of other reasons.
Try temporarily stopping any VPN's, proxies, firewalls, and browser extensions, and try using an alternative Internet connection, another WiFi router, or mobile data, or trying it from a completely different location, using a different computer (for GC Web and GE).
Tried already at mobile data. Nothing change. Later i will try on another wifi
