@hellfire103 I bet it’s the DAITA on your Mullvad, choose MultiHop instead with Wireguard, quantum resist. and obfuscation . Then use a Linux set from boot SOCKS5 as you desire. I hope it helps.
-- – run only 1 VPNetwork, you may have to set off periodicly your FireWall off and reboot.
@hellfire103 I’m glad it worked ;D
