Hey guys,
I am using 500 GB CUL plan in Haryana circle and as stated in my previous thread regarding telegram not working, I am facing a weird problem again that no website is opening up other than google and it products (Not opening up examples - github.com / mdbootstrap.com)
PS: Whatsapp and telegram are running fine. I am using adguard DNS for ipv4

Is anything I am doing here wrong? Or someone else facing same problem?

Thanks!
