Hello, I'm trying to install WinCC 8.1 on Windows Server 2022 64. However, I encounter an error every time. The runtime works correctly, but the web navigator gives the following error. I can't seem to fix the problem. Despite following all the steps in the link https://support.industry.siemens.com/cs/document/109814515/checklist-webnavigator-datamonitor-server-connection?dti=0&lc=en-AR and the installation guides, the navigator still isn't working. I assumed that version 8.1 was causing problems on Server 2022, so I installed 8.0. I got the same error again. I installed Server 2019. I installed 8.0, and it still didn't work. I installed 8.1, and it still didn't work.I've been doing research online, but I can't find any information because the version is new. I've reviewed Siemens's original documentation and applied the settings to the server, but it still gives different errors and doesn't work. How can I overcome this problem? We purchased a license to install it on a new server, and I want to install it on Server 2022. I would like your help in this matter.

Error is : 

HTTP Error 500.19 - Internal Server Error

Hi Murof,

I seem to have resolved the IIS issues. However, now the webnavigator won't connect. I'm getting the "failed to load https://XXX.XXX.XXX.XXX:4430/mainmenu.pd_" error. I don't understand. I'm doing everything according to Siemens' own documentation, but the system isn't working on Server 2022. I installed Server 2019 and it didn't work on that either. I wonder if Siemens claims these systems are compatible without testing them. Everything I've done is according to the original Siemens documentation. I've made all the settings as instructed, but I still can't get the webnavigator client to work.
