Cireson Portal

Issue: Chrome briefly says it can't find the Service Manager Portal website

Issue:

Chrome briefly says it can't find the Service Manager Portal website, then after a few seconds it navigates to the portal correctly.

Cause:

There is a compatibility issue with some versions of the Chrome browser and IIS with SSL enabled in Windows Server 2016.

Solution:

Note: The Service Manager and Service Management services must be installed on the same server, otherwise they will not function correctly.

To verify you're seeing this exact incompatibility, you can run Chrome with the following command:

chrome.exe --disable-http2

 

If running Chrome in this manner prevents the behavior, it can be solved on the server by adding 2 Registry entries.

  1.  Open regedit.
  2.  Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters.
  3.  Right click Parameters and Select New/DWORD.  Call it EnableHttp2Tls.  It should have a value of 0.  
  4.  Add another DWORD.  Call this one EnableHttp2Cleartext. It should also have a value of 0.
  5.  Reboot the portal server. 

Chrome should now navigate to the portal correctly.
