 ### Conclusion
 You should now be able to manage and contribute to your project! Good luck, and if you spot anything wrong with the wiki, or have suggestions, please log an issue about it [here](https://git.cs.sun.ac.za/Computer-Science/git-beginners/issues).
 
+## Troubleshooting
+### SSH connection check
+If you are struggling to connect to the server, try run `ssh git@git.cs.sun.ac.za` from the PC you want to connect from. For example, a **correctly** working key should produce the below output, except with your username or student number.
+```bash
+$ ssh git@git.cs.sun.ac.za
+Welcome to GitLab, @ajcollett!
+Connection to git.cs.sun.ac.za closed.                     
+```
+If things are not correct, you would see some sort of permission error. This means that either your password is not correct, your key is not in GitLab or your key has not been loaded into this terminal session. Try use `ssh-add` to load the key into this terminal session or try from a new terminal window.
