Can't play on mobile data anymore

I use mobile data because my home Wi-Fi is very trash, and never had any problems. Always played with friends, joined servers, etc… but suddenly, I can't do that anymore. I tried everything. I restarted my phone, cleared the cache, changed DNS, tried VPNs to see if the problem was the network itself, checked my Internet speed on speed test, changed Minecrafts settings to allow unrestricted mobile data use, logged off and back again to my Minecraft account and NOTHING worked. Please fix this. I just want to play with my friends in my damn short free time. (The two pics are here to both prove that the servers won't load and that I'm not dumb enough to not have toggled on the “use mobile data” option)
