Device not being created in FNO On prem 2018 R1
Device not being created in FNO On prem 2018 R1
Symptoms
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: com.opensymphony.xwork2.XWorkException: null at com.opensymphony.xwork2.util.DomHelper.parse(DomHelper.java:117) ~[struts2-core-2.5.13.jar:2.5.13] at com.opensymphony.xwork2.validator.DefaultValidatorFileParser.parseActionValidatorConfigs(DefaultValidatorFileParser.java:82) ~[struts2-core-2.5.13.jar:2.5.13] at com.opensymphony.xwork2.validator.AnnotationActionValidatorManager.loadFile(AnnotationActionValidatorManager.java:378) ~[struts2-core-2.5.13.jar:2.5.13] Caused by: java.net.UnknownHostException: struts.apache.org at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:184) ~[?:1.8.0_102] at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) ~[?:1.8.0_102]
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?
