• The firewall or antivirus software is preventing the service from starting by blocking back-end processes.
• The browsing cache on the machine is not cleared.

Solution or Workaround

Use one of the methods below to resolve the issue.

Note:
When using an ArcGIS Server print service with services added by the members to the portal through HTTPS, additional configuration is required. Any machine that runs the print service must be configured to trust Certificate Authority (CA) signed certificates from the site providing the HTTPS services. Refer to ArcGIS Server: Import the CA root certificate into the Windows certificate store for more information.

Start the PrintingTools service

Navigate to ArcGIS Server Manager > Services > Manage Services > Utilities. Identify the PrintingTools service and click Start.

Configure the firewall settings

To allow a connection to ArcGIS Server, remove the firewall rule on the machine blocking the connection. Refer to ArcGIS Enterprise: Firewall settings for more information.

Add exceptions to the antivirus software

Ensure the proper exceptions are in place for all the ArcGIS Enterprise directories. Refer to ArcGIS Trust Center: ArcGIS security for more information.

Clear the browsing cache

Clear the browsing cache on the machine to ensure a smooth performance of the browser. Refer to Google Account Help: Clear cache & cookies for more information.

Use a different browser

Use a different browser such as Google Chrome, Mozilla Firefox, or Microsoft Edge to log in to Portal for ArcGIS Map Viewer and print the desired web maps.
