Unable to setup Gitlab to Github mirroring

Hi, I am trying to setup mirroring for the leap/bitmask-vpn repo to github.com/leapcode/bitmask-vpn, i have followed the guide at: https://0xacab.org/help/user/project/repository/mirror/index and using SSH Authentication

but ultimately it ends up with the following error:

13:get remote references: create git ls-remote: exit status 128, stderr: "ssh connect to host github.com port 22: Connection refused\r\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.\n".

Screenshot of the error

Creating this issue to get an confirmation that mirroring is working in general for other repositories, as i am not able to figure out what might be the issue causing this.
