WinCC Unified Runtime V17 HTTP Error 503

I had the same issue when upgrading from v17 to v18.

I solved it by doing the following:

I created a new certificate with WincCC Unified Certificate Manager.

Then exported it to my desktop.

Then I imported the certificate inside Simatic Runtime Manager.

Selected the certificate inside Wincc Unified Configuration.

Hi,

in the German part of the forum, the following solution from the technical support was posted:

• Create a *.txt file and copy the following lines into it:

C:\Windows\System32\inetsrv\appcmd.exe uninstall module
UserManagementServiceLayer

net stop w3svc

net start w3svc

• Save, close
• Rename the file extension from *.txt to *.bat
• Start bat file via right click "run as administrator"

Kind regards
Stefan

Did u put this on the same line?

C:\Windows\System32\inetsrv\appcmd.exe uninstall module UserManagementServiceLayer

Run the bat from command prompt so u can see if u get any errors

DefaultAppPool has to be running

it worked for me, thank you very much 

I made it work.

The "DefaultAppPoll" in IIS wasn't running (don't know why). After the start everything works fine.
