If you're still experiencing issues after following these steps, please contact Siemens to help resolve your issue. They are the original source of this information and the manufacturer of the hardware. They should be able to assist you in making your runtime use relative paths instead of absolute paths.

On the Siemens WinCC Unified Runtime device install SIMATIC User Management Component (UMC) V2.0.
Change the file C:\Program Files\Siemens\Automation\WinCCUnified\config\config.level.
- Change the Url to the relative path /umc-sso/.
Change the file C:\Program Files\Siemens\Automation\WinCCUnified\SimatiUA\config.json.
- Delete the IP address from dnsname.
Change the file C:\Program Files\Siemens\LocalUserManagement\etc\umcd.cfg.
- Delete the IP addresses from the paths so that only the relative paths remain at idpAddress, idpAuthSite and idpAddress.
Change the file C:\Program Files\Siemens\UserManagement\WEB\umc-sso\config\configuration.json.
- Change UMCDllFolderPath to "C:\Program Files\Siemens\Usermanagment\BIN".
Open regedit and go to folder Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\User Management\WebUI\Settings.
- Change the registry value of idpaddress to /umc-sso/.
Restart the IPC.
