VPN Issues While Using Phone's Hotspot #520

Closed zoroglu closed 3 months ago

zoroglu commented 3 months ago

When I connect from the computer to the phone's internet, I can't do vpn. I can make a vpn with a different internet provider other than the phone.

openvpn version: OpenVPN 2.5.1 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on May 14 2021 library versions: OpenSSL 1.1.1w 11 Sep 2023, LZO 2.10

Debian GNU/Linux 11 (bullseye) 64-bit

My Internet provider is Vodafone I tried to connect with a different Phone, but it still doesn't connect

From the looks of it, the TCP connection can be established, but is torn down immediately (0.1 second later, Connection reset) by "something". Since it works using other ISPs, this sounds like a problem - or "feature" - in Vodafone's network.

You can try moving the OpenVPN server to a different Port (tcp/443 often works because "this is https port, do not mess with it", or try classic udp/1194 "this is OpenVPN, do not mess with it"). Besides that, there is not much what we as OpenVPN developers can help you here.

(Side note: this is a bug tracker for bugs in OpenVPN, not for operational or config questions)
