Whilst creating a device in FNO on premise 2018 R1 it has been observed that an error is produced whilst selecting an account. In the flexnet.log the error is:
2018-10-01 05:23:56,955 [default task-6] ERROR (interceptors) [ADMN] SecurityInterceptor: Failed to execute Action:

Cause
This issue is caused by restricting FNO so that it cannot connect to the internet. This may be due to a proxy or a firewall.
Resolution
To resolve the issue you would need to allow the following URL's in the firewall or proxy :
*.flexera.com, *.flexnetoperations.com, struts.apache.org, jakarta.apache.org, tiles.apache.org, *.hibernate.org, hibernate.sourceforge.net, *.jboss.org, *.springframework.org, *.root-servers.net, schemas.xmlsoap.org, w3.org, xml.apache.org, xmlns.jcp.org, *.flexerasoftware.com and most importantly localhost
Can you provide more clarity on why some of those hosts are required? For example, hibernate.sourceforge.net redirects to hibernate.org when accessed via a web browser, and their web page suggests they use Github, not SourceForge?
