You may have tried to join your Minecraft server and been rejected due to the error “Failed to verify username” or “Invalid Session”. This issue is normally because the client’s launcher failed to authenticate with Mojang’s session servers. Luckily, you can fix this error with just a few steps.
You may also be running a non-premium version of Minecraft. If you did not pay for Minecraft, you will not be allowed to join most servers due to the server running in online mode, however, it can be changed to offline mode fairly easily.

If you are using premium Minecraft and have already followed the steps on to resolve the error and still cannot join, try restarting the server.
