Hello to all the forum.

I can't open tia administrator, the error message is the following:

CANNOT REACH THE SITE

connection denied by localhost

ERR_CONNECTION_REFUSED

The version of this administrator is v3 sp3

Thanks for any answers.

Hi pitbrown

From my experience, this error can appear due to many factors 

-Have you temporarily disabled antivirus and firewall on your computer? Are you using admin rights?

-Check that you do not have older versions of TIA Administrator installed.

-Restart the SiemensTiaAdminV3 service. In case you have V2 active, stop it.

Also, check this FAQ: Why is it not possible to log in to TIA Administrator with a Microsoft account (cloud account)?

Good luck!
