Getting a Blank page with 503 "Lazy Load error" as covered in 

https://knowledge.broadcom.com/external/article?articleId=125671

https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/it-operations-management/application-performance-management/10-7/troubleshooting/application-monitoring-troubleshooting/team-center-loads-blank-page-after-login.html

Neither of these solutions are working.

Environment

Release : 10.7.0

Component : APM Agents

Resolution

Changed the URL in the IntroscopeEnterpriseManager.properties pointing to the root of the Enterprise Manager REST API to be a hostname not an IP. Certificate was set to match on hostname not IP Address. Adding a certificate to match on server IP as well would resolve this.

Example:
#introscope.webview.enterprisemanager.rest.base=https://x.x.x.x:8444/apm/appmap changed to 
introscope.webview.enterprisemanager.rest.base=https://hostname,subname.companyname.com:8444/apm/appmap

Additional Information

Important clue:
Webview log has errors about "java.security.cert.CertificateException: No subject alternative names matching IP address 10.60.168.39 found
