404 error when attempting to access Confluence

[Justin Jacobs]

Hello!

We have had Confluence successfully running on an Amazon EC2 instance for several months (running Amazon Linux).  I recently used CloudWatch/Lambda to schedule start/stop times for the instance so that it is only available during business hours.  I also followed this guide so that Confluence starts automatically when the instance starts:

https://confluence.atlassian.com/doc/start-confluence-automatically-on-linux-183148.html

After restart the service does indeed start but when I navigate to the server's address I receive a 404 error, page not found.  I get the same error when navigating via the server's elastic IP address.

Running a 'wget' on the server produces this:

wget http://localhost:8090
--2017-04-13 21:55:16--  http://localhost:8090/
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:8090... connected.
HTTP request sent, awaiting response... 404 Not Found
2017-04-13 21:55:16 ERROR 404: Not Found.

I undid the steps outlined in the above article and tried starting Confluence via the start-confluence.sh script, it starts successfully but I am still unable to access it in my browser:

Server startup logs are located in /home/ec2-user/atlassian/confluence/logs/catalina.out
Using CATALINA_BASE:   /home/ec2-user/atlassian/confluence
Using CATALINA_HOME:   /home/ec2-user/atlassian/confluence
Using CATALINA_TMPDIR: /home/ec2-user/atlassian/confluence/temp
Using JRE_HOME:        /home/ec2-user/atlassian/confluence/jre/
Using CLASSPATH:       /home/ec2-user/atlassian/confluence/bin/bootstrap.jar:/home/ec2-user/atlassian/confluence/bin/tomcat-juli.jar
Using CATALINA_PID:    /home/ec2-user/atlassian/confluence/work/catalina.pid
Tomcat started.

I am afraid that I have exhausted my ability to troubleshoot this by myself.  I am hoping someone can help me.  I have all the logs and can provide any additional information that may be helpful.

Here is where I would start:

• Open the log at <Confluence_Home>logs/atlassian-confluence.log 
  (The <confluence_home> directory is the path defined in the following file: <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties)
• Search for "Starting Confluence"
  scroll down past the initial startup messages, which include system info and a list of plugins
  look for entries that start with ERROR
• Do the same with the <Confluence_Install>/logs/catalina.out.
