PCs that use Chrome as the Default Browser Unable to Login to Noah ES

It has come to HIMSA’s attention that the latest Chrome browser update (version 123.0.6312.59) is preventing the Noah ES Client from starting.

The error shown in the Chrome Browser is “This site can’t be reached” Err_Connection_Refused.

The Noah login window will show an error in red text: “Invalid login. Please try again”


HIMSA is actively investigating the cause of this issue and will post updates here as soon as they are known.


  • The issue does not occur with the Edge or Firefox browsers.

  • Download and install either the Edge or Firefox browser

  • Edge or Firefox must then be set as the default browser.

Changing the default Browser in Windows

If you already have Edge or Firefox installed, select Windows Start and type “default” and select Default Apps. The Default Apps settings screen will appear. Search or find Edge or Firefox in the list of apps and select it. The top of the next window will then provide a choice to “set default”. Close all open Noah Windows and try logging in again.
