confluence server started but ERR_CONNECTION_TIMED_OUT

[Yong Xin Choon]

Hi Confluence Team,

We setup a JIRA & Confluence Data Center on our servers. JIRA works fine, but Confluence cannot access. Always shows 'ERR_CONNECTION_TIMED_OUT';

1、Confluence server started: catalina.out logs:

2、Request from browser is received by confluence server: conf_access_log.2023-11-10.log:

3、but we cannot access confluence: (not find any error logs)

So, could you help us with this issue? 

Thx/Br

Hi Yong,

First, I would also like to warn you that Confluence version 7.17.4 is vulnerable - CVE-2023-22518 - Improper Authorization Vulnerability In Confluence Data Center and Server and you need to upgrade to at least version 7.19.16 as soon as possible.

Did you set the <confluence-install-folder>/conf/server.xml file correctly? Are you using Apache / NGINX before Confluence? Do you have DNS forwarding set up correctly?

Hi Pavel, 

Thanks for your response, we're planning to upgrade the confluence server to 7.19.16. In these two days. Thanks again.

We have NG before Confluence, and we checked the NG logs, it seems NG forwarding the browser request to our Confluence server is all right.

That's why we post our conf_access_log above, it shows NG's request was received and then Confluence server forwarding it to /bootstrap/selectsetupstep.action 

But we haven't found any error logs on Catalina.out.

Below is our Confluence server.xml, whether it helps:

Hi @Yong Xin Choon,

You will need to properly edit the server.xml file - comment out the current connector block and uncomment the part for NGINX. Please see to Running Confluence behind NGINX with SSL 

I think you will now have Confluence accessible at http://localhost:8443.
