Hello,

We are facing problems with IIS when it use https (SSL 443) to manage an application web running on IIS, once you open and login into it crashes and the server insta reboot. The dump log file shows:

CUSTOMER_CRASH_COUNT: 1

PROCESS_NAME: w3wp.exe

If change to http (80) it works fine....

Any idea?

Thanks

    Hello

    Thank you for your question and reaching out. I can understand you are having query\issues related to IIS crashed.

    1. Please verify that port 443 is not being used in any other IIS website or should not bind to any other IP address
    2. Disable any Antivirus program or Windows firewall you may have for temporary purpose.
    3. Run sfc /scannow from elevated prompt.
    4. Run below DISM commands from elevated prompt.

    DISM /Online /Cleanup-Image /CheckHealth

    DISM /Online /Cleanup-Image /ScanHealth

    DISM /Online /Cleanup-Image /RestoreHealth

    Hi @Bordallo Gonzalez, Samuel

    According to your description, if you used DebugDiag or WinDbg to analyze the crashes dump file. It should contain more detailed crash information.

    What is known is that w3wp.exe crashes when port 443 is used. This can sometimes cause IIS to crash when port 443 is bound to multiple sites. You can check applicationHost.config to see how port 443 is bound. Remove the reference to port 443 from the other site and restart IIS, then test again.

    If there has any antivirus or similar software on your machine. Please completely uninstall it, restart the machine and test again.

    Hope my answer can help bring you. If there are other questions, please use the analysis tool to provide more detailed crash analysis information.

    Best Regard,
