TroubleShooting

Wanted to see if it was just sending updates that are failing.

Let us see what happens with pulling files from GitHub.

fatal: Could not read from remote repository.

Please make sure you have the correct access rights

Network Client Diagnostic Tools

Please reach for network client diagnostic tools.

The most basic network port diagnostic tools such as telnet will suffice.

Particulars:-

1. Host:- Github.com
2. Protocol
   • SSH ( TCP 22 )

Confirmed that SSH Network Protocol-Traffic is indeed blocked.

 

Remediation

Opened up SSH Protocol ( TCP 22 ) on the network equipment.

 

Summary

Obviously will not have this problem if we are using HTTP to connect to GitHub.

The problem is manifesting due to the fact that we are using SSH.

Please continue to use SSH; as it is a more secure.
