I'm trying to setup ssl with an self singed certificate on ubuntu 14.04. I followed the steps as described in the confluence manual: * $JAVA_HOME/bin/keytool -genkeypair -alias tomcat -keyalg RSA * sudo mv .keystore /.sslcert * Uncomment " keystoreFile=" " /> * change the default domain within confluence settings * Restart the server After that I can't access the server anymore it just quits: ERR_CONNECTION_REFUSED Could you please help?

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

change the default domain within confluence settings
Restart the server

After that I can't access the server anymore it just quits:
ERR_CONNECTION_REFUSED

Could you please help?

It seems that installation of the certificate broke the acces right to the atlassian folders. Thats quiet strange. Some other guys had this problem too.

sudo chown -R confluence:confluence /opt/atlassian/confluence/   
sudo chown -R confluence:confluence /var/atlassian/application-data

EDIT: That does not seem to be the issue. The problem actually is that the startup of the server takes very long (up to 5 minutes). So after restarting the server I noticed the follwing:
- CPU load high
- Timeout first
- After 2 Minutes: Error 500
- After 5 Minutes: CPU load decreases -> Atlassian loads fine and fast

--> So waiting fixes the problem or maybe better switch to a real hardware instead of a xen virtualised enviroment (2 GB Ram, 3 Cores)

Thanks for your help!

Check out the following:

http://www.digicert.com/ssl-certificate-installation-tomcat.htm

I used those without issue for self signed and 3rd part signed.

The CPU Load is also very high during startup and then the error occurs.
