How to fix error "License Manager Error -5"

Hi, I'm using MatLab WebApp Server R2022b.

My server was running smoothly until yesterday.

Today, I installed MatLab WebApp Server R2023a to upgrade my server.

However, now I'm encountering an error message that says "License Manager Error -5: Cannot find a license for MATLAB_Web_App_Server."

I have checked my license, and it appears to be normal.

Could you please guide me on how to resolve this issue?

Here is my log.

[Walter Roberson]

Are you thinking that you are using a local license or a network license to a remote server?

The diagnostics imply that it is trying to start up a local license manager but failing to do so.

Given those diagnostic messages, one of the first experiments I would do would be to reboot.

Fixing this issue would require looking at your license file and license manager log file, neither of which you want to post publicly. I'd recommend reaching out to MathWorks official support since they can handle that sensitive info.
