Aloe Express Server Error

Has anyone experienced “Aloe Express Server Error: Code: 105”? I cannot seem to locate the error codes anywhere. I’m using AE 4.01 on Windows and I’m just trying out the demos without any changes. I’ve also tried it with the firewall disabled but that didn’t seem to work either. Thanks in advance.

TCPSocket 105 - Address already in use

Thank you Phillip!

To clarify for future readers - presumably the port you chose for the server was already being used by a random Windows app?

Thanks Garry. Actually, for me it was another Xojo app where the IDE had crashed earlier but the app was still running in the background. Even after I ended the task through task manager, it was still an issue so a reboot took care of it.
