I was using the Google Stun server by IP 74.125.143.127, but since 21/09/2021 it seems Google changed the IP of DNS stun.l.google.com. I know I should use DNS rather fixed IP. Any guys have some confirmation about the IP change? tks

Yes. That's the answer. Full stop. Don't hardcode IP addresses to services in your app. The whole point of DNS... well, you know this right?

Some recent DNS lookups:

stun.l.google.com:   74.125.197.127
stun1.l.google.com: 173.194.193.127
stun2.l.google.com: 172.253.112.127
stun3.l.google.com: 173.194.77.127
stun4.l.google.com: 172.217.215.127

Testing the old IP you referenced that's not in the DNS entries above:

>stunclient 74.125.143.127
Binding test: fail

Testing the IP address that's currently being returned:

>stunclient 173.194.193.127
Binding test: success
Local address: 192.168.1.18:55004
Mapped address: 1.2.3.4:55004
