Environment : This article applies to all Aruba controllers and coder versions.

 

Sometimes we cannot login into the controller WEBUI. Browser throws an error:
"can't do cli: SID Validation failed"

Please see the screenshot below:

We also see the following error messages in the CLI:
httpd: SID Validation failed GET URI:/screens/cmnutil/execFPCliCommand.xml

 

This issue can happen if we upgrade the controller and try to login to WEBUI after the reboot.
If this issue happens, we must clear browser cache and try again.
