Technical Tip: EMS Console displays message Bad Request (400) when accessing through the browser

Description

This article describes that EMS Console displays the message Bad Request (400) when accessing through the browser.

Scope

FortiClient EMS On-Prem.

Solution

If accessing EMS on Prem using FQDN through the browser, it may display the message Bad Request (400).

To resolve:

Ensure the FQDN is resolved to the correct EMS IP address. This can use nslookup and ping commands for checking.

Check the EMS setting: Login into EMS Console (using the application) -> System Setting -> EMS Settings and ensure the setting for 'Remote HTTPS Port' is checked (ticked).

Refresh the browser and it should show the display console as expected.

As a general recommendation, always make sure the FortiClient EMS services are UP and running at the Windows server:
