Issue:
We have an issue with VANWEBUI after upgrading to R1405. 
The messages in the VANWEBUI job log point to the apache catalina server startup:

Feb 08, 2019 12:41:48 PM org.apache.catalina.startup.Catalina start 
INFO: Server startup in 115085 ms 
Feb 08, 2019 12:41:49 PM org.apache.catalina.core.StandardServer await 
SEVERE: StandardServer.await: create[localhost:18005]: 
java.net.BindException: EDC8116I Address not available. 
at java.net.PlainSocketImpl.socketBind(Native Method) 
Resolution:
2 ways to fix:
1. With installation wizard , on section shutdown port number need to be set to -1
2. Manually edit conf file in tomcat run-time environment, ( Example : /runtime/apache-tomcat-8.5.31/conf/server.xml) , ensure that line look like this And start web ui task again
We have updated the server.xml and now the Started Task is working again.
