Hi @Hamid Akbari ,

Is this a new installation? If not, any recent changes or updates?
Have you tried with a different admin account and different browser?

If still issue happens, please check the below,

1.Check if MSExchangeECPAppPool is running
2.Check if the Exchange backend website has the certificate - > go to IIS -> Expand Sites -> Exchange Backend -> Click on Bindings on right side -> https 444 -> Check if it has the certificate with name "Microsoft Exchange"

Also, please share the complete error by removing the personal information.

If the above suggestion helps, please click on "Accept Answer" and upvote it.

Hi @Hamid Akbari ,

What’s the version of your Exchange 2016?
And are there any related error messages in Windows Event Logs? Please share with us and cover the personal information.

In addition to what AshokM said, you can try to reset the virtual directory.
Go EMS and run the following commands:

Remove-OwaVirtualDirectory "ServerName\owa (Default Web Site)"
New-OwaVirtualDirectory -InternalUrl https://Server.Domain.com/owa
Restart the IIS and check if it works.
