BAC is inaccessible, throwing a blank page instead the usual login page.


BAC is returning a blank page when trying to access it through URL that uses port 80: http://<Gateway>/topaz. BAC is accessible via port 8080 when using URL http://<Gateway>:8080/topaz


Problem with port 80 points to a problem with the webserver

root cause of the problem is Tomcat taking too long to start what makes webserverguard to restart the web server every few minutes

On the Gateway server:
  1. open the file   <BAC>\conf\supervisor\nanny\webserverGuard.nanny  and change the line "enable=1"  to  "enable=0". This will prevent webserverGuard service to start when the Gateway is restarted. 
  2. stop BAC Gateway
  3. restart the web server
  4. restart BAC Gateway
