Cannot access Confluence after installation : Page cant be opened

[Deleted user]

I have seen a couple people had this problem, but a solution did not come to me.

I installed confluence on an aws instance ( ubuntu 16.04 ) and as far as i read the logs, i do not see an error. 

i followed the instructions on https://confluence.atlassian.com/doc/installing-confluence-on-linux-from-archive-file-255362363.html

When i start the process i geht following lines in Terminal:

To run Confluence in the foreground, start the server with start-confluence.sh -fg

executing as current user

If you encounter issues starting up Confluence, please see the Installation guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide

Server startup logs are located in /var/www/html/confluence/logs/catalina.out

Port 8090 is allowed...

As is suppose, that is a beginners fail - where else can i find a source for this error?

[Suhas P · Accepted solution]

I am not AWS expert but from the basics, Please check if you have set up Security Group, Inbound rules correctly. If you don't set Inbound traffic, you cant access it.

Thanx for your fast reply. i added port 80, 443 and 8090 for outbound and have no restrictions for inbound. 

I will try to find other info in the server logs maybe

I have also seen problems when having chosen wrong subnet, VPC or Availability zone. Make sure all components you are using correct ones and in the correct zone. It seems like it is not application issue but Infrastructure config. You should contact a local AWS expert, they can fix these issues quickly.

i created from scratch another instance and used this installation guide:

https://wiki2.easycloudsolutions.com/display/ECW/How+to+Install+Atlassian+Confluence+on+Amazon+EC2

Now it works, i guess it was really an error in the aws configuration.

Thanx.

It was surely AWS config error. Its very usual to encounter such problems when you are trying out for the first time. We often do small unnoticeable errors which results into spending hours or days to fix it. ;)
