One interesting thing I noticed was that when I was parsing the omegle domain name properly, the DNS server returned me an IP of 104.23.142.25.
I can access this address normally, even on the X300B.
But when I tried domain resolution with the X300B, I got the wrong address
After I configure DNS encryption, the domain name is resolved correctly
I want to confirm that you have tried DNS encryption and confirmed that it does not solve the problem?
