## Symptoms

- * You cannot browse to the Management Server's SmartView Web GUI with port 443 or 4434. The browser returns:   
  `502 proxy error`   
  or   
  `404 not found error`

  <br />

* When you click SmartConsole -\> Logs \& Monitor -\> open a new tab, a `Loading SmartView` error appears, and the operation fails with a timed-out error after a long time.

* When selecting a Server object in SmartConsole -\> Summary tab -\> License Status -\> in Device \& License information -\> License Status tab shows the same SmartView error - `Loading SmartView` error appears, and the operation fails with a timed-out error after a long time.

* It takes more than ten minutes for the `api status` command to return the results with all the processes started. The command may return this error:  

  `API readiness test FAILED. The server is down and unable to receive connections`.

* **Notes** :
  * The Endpoint Policy Management Blade is enabled.
  * Gaia SSL port may change to 4434.
  * The issue persists when you disable the Endpoint Policy Management Blade.
  * Gaia GUI Clients is configured to "Any", or the client workstation IP is on the GUI Clients list.
  * The */web/conf/extra/httpd2-smartview.conf* file is the same as on other working Management Servers.

## Cause

The *uepm_gaia_ssl.conf* configuration file is corrupted.
