Hi there I've been using FTTH BSNL there was once a MTU issue that happened to me, after looking at BSNL FTTH DNS PROBLEM | BSNL Bharat Fiber it was fixed finally, thanks to y'all actually the issue here is I am using Google DNS response time >24 ms but the famous game PUBG Mobile seems to have some issue running using the FTTH ASAP I switch to mobile data its fine, but I kind of need it on the WiFi because the ping on wifi is 20 ms, I've checked sometimes it works sometimes it doesn't at end I'm thinking that it might be a DNS issue, because every other service works fine Netflix, Prime Video everything ping to speedtest servers are even fine, this one thing that messes it up. I want to know if this has been happening to you or you have a fix for this.
Regards
