I am unable to access GitHub either from the terminal or from any browser or device when I am using the WiFi. I am able to pull, push or execute any command related to Github from the terminal and access GitHub on the browser when I use the hotspot I created from the mobile.

And the other way that I am able to access GitHub on the browser is using VPN. When I use the git commands using the mobile hotspot I get the same error but I delete the key using the method they have mentioned and follow the process and enter the password and everything is fine. When I use the same method using the WiFi even though I enter the password correctly it denies me access.

The error I showing up on the terminal when I'm using wifi and executing any git command:

```
