Spectrus JS: Processing Server is not running or is misconfigured, Bad Gateway error.

Description

If you can sign in but still receive a Bad Gateway error, the issue may be related to the Processing Server.

Solution

Open your browser’s developer tools. The keyboard shortcut may vary depending on the browser you are using.

Open the Network tab and enable Preserve log.

If the failed request uses the /api path, check the Processing Server status in Server Manager Console (SMC) and start it if needed.

After the Processing Server starts, refresh the page and sign in again. You may see this:

If the response now comes from the Processing Server, communication is working, but the server may still reject the request because of an authorization or configuration issue.

In some cases, the Processing Server is running but its internal configuration is incorrect.

Review the Zathras.ini configuration file. It is usually stored in the following location:

\\SpectrusJS\SpectrusJS.SRV\ZATHRAS>

Correct any configuration issues, then restart the Processing Server from SMC.

Open the Spectrus JS link again after the restart.
