Confluence won't open in browser

Confluence won't open in browser

Hello everyone,

I've just installed Confluence and connected to Jira(It's on a separated server) successfully. It was so slow at the first time but it got faster after a while. I'm running it on Lightsail (40GB SSD) and I set up SSL using this doc and I've opened Confluence successfully again but it told me to change the base URL because I was forwarding the port due to SSL setup. So I did it and it stopped working. I checked the logs and I couldn't see any problem. The problem is: When I try to access my Confluence via browser, it just stuck. I'm accessing it on 8090 port and I've waited almost 10 minutes and it didn't open. Now it's all broken.

My server has 1GB memory but I created 6GB swap and it was all working until the base URL change. BTW, I changed it again to the default URL in the DB.

Which is: conf.example.com:8443 to conf.example.com:8090

Can anyone give me a hand to fix this, please?

Here's my log:

Hi,

So confluence was working when your URL was HTTPS://your.example.com:8443? But when you changed the base URL to http://your.example.com:8090, it no longer loads? I assume you are entered the base URL in the browser. What does your <confluence-install-dir>\conf\server.xml file look like?

Since 8090 is usually the default port Confluence ships with, maybe restore the default out-of-box server.xml, and restart Confluence. It could even though your base URL is updated, it server.xml is looking for HTTPS/SSL, Maybe this will help - https://confluence.atlassian.com/doc/change-listen-port-for-confluence-165823.html.

Thank you for your reply.
Actually it's the opposite. It was working on http://your.example.com:8090. Then I set up SSL and redirected to HTTPS://your.example.com:8443 and then is stop loading. I entered the both URLs (http://confluence.example.com:8090 <-- This is the default base URL and https://confluence.example.com:8443 <-- this is the redirected URL) to the browser. I've tried both of them but didn't work. I changed the base URL back to http://confluence.example.com:8090 but still no luck. Also, I restarted the app and the server many times. Changing ports didn't help.

Hi,

From the file above, it looks like it is still trying to connect on port 8443. Try using this server.xml below. It is the shipped version with Confluence 7.4. It only points to pot 8090. Drop this file in your <conf> directory and restart Confluence. Hope this works:

<Server port="8000" shutdown="SHUTDOWN" debug="0">

Comment

I've tried but didn't work. Also, it was working with this config. I'm redirecting from 8090 to 8443. Everything just broken after the base URL changes

Comment

I set up everything with the same steps and changed the base URL again and it worked but it's too slow. Is this because of the swap? I've heard that some components etc. won't use swap. Is this the cause of this slow performance? It's impossible to use it like this. I mean it tooks 40-50 seconds to open a page
