With the tyGraph Pages Engine, we capture user telemetry in realtime as the user browses SharePoint Online. The engine uses our own API and CDN hosted in Microsoft Azure to provide configuration information. It also requires Azure Application Insights. In order to accurately collect telemetry, the Engine must be able to connect to all of these resources.
Please ensure that all users on your network can access the following URLs:
We have had reports from some customers that these URLs may need to be explicitly whitelisted in your cloud firewall (i.e.: Netscope, Zscaler) in order to avoid connectivity issues such as CORS errors. If you suspect, you are having connectivity issues for specific users or locations, you can try using the tyGraph Engine Health Check to verify connectivity.
