    Hi @Kelvin Cheng,

    From the screenshot you are accessing ECP with url

    Below are a few questions in order to narrow down this issue:

    1. Is it a fresh install of Exchange? If not, what changes have been done before this issue?
    2. If you access ECP on the Exchange server with https://localhost/ecp, would this issue persist?
    3. Does Exchange Management Shell work for you?
    4. Does Outlook on the web (https://localhost/owa) work for you?

    Thanks in advance for the information.

    1. We used Exchange long time. After removed the SSL certificate, the problem happened. Also, we had main and backup mail server, but the main server was failure now. So, we already turnoff the main server.
    2. When we access by https://localhost/ecp, it will jump to "https://localhost/owa/auth/logon.aspx?url=https%3a%2f%2flocalhost%2fecp&reason=0".
    3. Yes, the Exchange Management Shell is working.
    4. We also cannot access to (https://localhost/owa).
