Woiden Hax-OpenVZ VPS visit GitHub failed "port 443: Connection timed out" Troubleshooting

The network environment of Woiden VPS has changed, and direct access to GitHub often encounters the following problems

curl: (28) Failed to connect to api.github.com port 443: Connection timed out

Solution:

Open TUN;

Install WARP to cover the useless IPv4 outbound on woiden;

Modify the /etc/wireguard/wgcf.conf to make original IPv4 inbound for SSH still available;

Do what you want (access GitHub?)

Process:

Open TUN

https://woiden.id/vps-control

Restart your VPS to make sure TUN is opened.

Some preparation

apt update 

apt install -y curl screen

screen

WARP installation

Install WARP to cover the useless IPv4 outbound on woiden;

Modify the /etc/wireguard/wgcf.conf to make original IPv4 inbound for SSH still available;

bash <(curl -L https://github.crazypeace.workers.dev/https://raw.githubusercontent.com/crazypeace/warp.sh/main/warp.sh) 4 && bash <(curl -L https://github.crazypeace.workers.dev/https://raw.githubusercontent.com/crazypeace/warp.sh/main/wgcf_postup_postdown.sh)

* It's a very long command. And we used screen to make sure that even we disconnected SSH the command will continue running to finish the setting. 

Do what you want

You can access GitHub now.

PS

If you meet this ERROR below

ERROR: (wgcf) 2022/09/15 07:18:35 Failed to create TUN device: operation not permitted

This means you didn't open TUN mode successfully. If you opearted TUN mode, please try restart your VPS.

If you alway get stuck on the step below

[INFO] Starting WireGuard...

Created symlink /etc/systemd/system/multi-user.target.wants/wg-quick@wgcf.service → /lib/systemd/system/wg-quick@.service.

Then you can try change your system to Debian 11
