AdGuard DNS issue

Hi there.
Can someone help pls?
I am not able to test upstream - getting error like this:

2022/02/20 16:26:48.272877 [info] upstream “https://dns.adguard.com/dns-query” fails to exchange: couldn’t communicate with upstream: initializing http client: initializing http transport: bootstrapping https://dns.adguard.com:443/dns-query: lookup dns.adguard.com: read udp 192.168.1.3:35119->1.1.1.1:53: i/o timeout

Or maybe if I want to refresh filters, I am getting this king of error:
2022/02/20 16:32:51.293790 [info] requesting filter from https://adguardteam.github.io/AdGuardSDNSFilter/Filters/filter.txt, skip: Get “https://adguardteam.github.io/AdGuardSDNSFilter/Filters/filter.txt”: initializing http client: initializing http transport: bootstrapping https://dns.adguard.com:443/dns-query: lookup dns.adguard.com: read udp 192.168.1.3:38249->1.1.1.1:53: i/o timeout

Runnig UDM Pro, and not sure if I have to configure rules somehow or not.

Thanks for any hint…
