+=== Common issues and how to solve them
+
+==== If you deleted the "@internal1" key from your profile
+
+ As long as you have at least one public key configured in your profile, use your SSH client to connect to {{{gw.orbit-lab.org}}} and run the following commands there. You do not need to make a reservation in the scheduler for this.
+
+ '''Make sure you are connected to gw.orbit-lab.org and running all of the following commands on gw.orbit-lab.org!
+{{{#!shell-session
+rm ~/.ssh/id_rsa
+rm ~/.ssh/id_rsa.pub
+ssh-keygen -t rsa -C "@internal1"
+}}}
+
+ Press 'Enter' at every prompt so that the default filename (id_rsa) and no password is used.
+
+ Then type the following command:
+{{{#!shell-session
+cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
+}}}
+
+ The internal key should now be restored.
+
+==== Warning about "authenticity of host can't be established"
