My phone (xiaomi redmi 6 miui 11) suddenly can’t connect to some apps without VPN. I can use chrome and other google apps, whatsapp, instagram, twitter with or without VPN. But I can’t connect to internet without using VPN to these apps: games, discord, line and webtoon.
My computer and other phones are just working fine with the wifi.
I have tried “reset network settings” and “factory reset”. But the problem is still there.
The wifi that I connected to has this settings: (Proxy: none), (IP settings: DHCP)
What should I do?
Is this maybe because my phone got port blocking?
