Troubleshooting Web-based Clients

Unable to Access Configuration Hub After Upgrading Web-based Clients
Description
After you upgrade Web-based Clients, you cannot access Configuration Hub.
Workaround
Clear your browser cache.
Error Occurs When You Try to Access Web-based Clients
Description
If you have logged in to Operations Hub, and then if you try to access Web-based Clients, and vice versa, an error occurs. This is because the user credentials of the first application to which you have logged in are used to log in to the other one as well.
Workaround
Try one of the following steps:
  • Add the scopes of each application user to the other application.
  • If you log in to Web-based Clients first, on the login page of Operations Hub, re-log in with the Operations Hub user. If you log in to Operations Hub first, log out of Operations Hub, log in to Web-based Clients, and then log in to Operations Hub, using the credentials of the respective users for each application.
Unable to Access Web-based Clients
Description
When you upgrade Historian, after installing Web-based Clients, a message asking you to restart the machine does not appear. Because of this, sometimes, you cannot access Web-based Components such as Configuration Hub, Trend Client, the Web Admin console, and REST APIs.
Workaround
Restart the machine, or start the following services:
  • GE Historian PostgreSQL Database
  • GE Historian Tomcat Server
  • GE Operations Hub Httpd Reverse Proxy
  • GE Operations Hub Proficy Authentication PostgreSQL Database
  • GE Operations Hub Proficy Authentication Tomcat Web Server
  • GE Proficy Authentication External IdP Configuration Service
  • GE Security App Service
Certificate Issues When Trying to Log in
Workaround
Connect to a Remote Proficy Authentication Service
Web-based Clients are not connected to the Historian server
Workaround
  • Ensure that the Enforce Strict Client Authentication and Enforce Strict Collector Authentication options are disabled in the Data Stores Security section in Historian Administrator.
  • Ensure that the Proficy Authentication URL used by Web-based Clients matches the one you provided while installing the Historian server. If not, change the Proficy Authentication server so that the Historian server points to the same Proficy Authentication server as Web-based Clients.
Clients or Users Not Created
Description
Clients or users are not created because the required services were not running during the installation of Web-based Clients.
  • An error message appears when you access Web-based Clients or Trend Client.
  • The visualization client is not found. The following error message appears: No client with requested id: historian_visualization
  • When you attempt to log in to Proficy Authentication, a message appears, stating that the credentials are incorrect.
Workaround
Configure Web-based Clients to point to a different Configuration Hub and Proficy Authentication instance.
The Reverse Proxy Service Stops Working
Description
If you install iFIX on a machine that has Historian Web-based Clients, the reverse proxy service stops working.
Workaround
Restart the reverse proxy service - GE Operations Hub Httpd Reverse Proxy.
