<![CDATA[New Install, Can't access http page]]>Good afternoon,

I have a new install of the 3.5.0-beta.3 running on a brand new install of CentOS 7.
Oracle's JDK 1.8 is installed and running. JAVA_HOME directory is correctly set.

[root@localhost Mango]# $JAVA_HOME
-bash: /usr/local/java/jdk1.8.0_181: Is a directory

I can run the ./ma.sh start and Mango will start with no errors and no issues. However, I can't access the html page running on port 8080. I did not change the default port. The browser's built-in Network analyzer tool simply says unable to establish a connection.

Any ideas what could be causing this? The OS shows the process running with no issues.

[root@localhost ~]# /Mango/bin/./ma.sh start
MA_HOME is /Mango
[root@localhost ~]# ma-start: MA started with Process ID:  20420

I have a new finding. I now get a response when accessing the http page via command line from the server ( using the wget -p http://localhost:8080 command), but can't access it from any of our other servers running in the same LAN. So now I no longer think this is an issue with the Mango instance, but rather a network/firewall issue most likely.

I will look further into it and report back with my findings after the weekend. Thanks again for the prompt response!

Have you checked for an env.properties file that could be setting it to a different port? Mango/overrides/properties/env.properties and Mango/classes/env.properties

If you have accessed a Mango over SSL that had the same HTTP port (could have a different SSL port) you would need to delete your cookies for the host. But, that would manifest as no ability to login, not an inability to load the login page. I just did an upgrade and am certain the Mango/classes/env.properties file is set to port 8080 (as it always was) and that no env.properties files are errant on the classpath. I would advise checking all files you find in

find /Mango -name env.properties

But theoretically it is possible for an env.properties file to be in a jar and cause issues. Having just upgraded an instance, I am confident that is not what is happening.

Your log looks like a successful boot. You could probably see open ports owned by java with netstat -tap | grep java

After that we can start wondering about firewalls. It looks like you started it as the root user, so I wouldn't expect any Linux permissions issues.
