HTTP: failed to make connection to backend: 127.0.0.1

Added by Bernd Müller over 9 years ago

EDIT: Solved it. Seems like you should use utf8 as encoding, not utf8mb4 :( Maybe this should be added to FAQ or installation instructions.

Hi,

I try to install openproject with packaged installation, but I get an error when I try to access openproject.mydomain.tld:

This is the output in apache error.log:

(111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:6000 (127.0.0.1) failed
AH00959: ap_proxy_connect_backend disabling worker for (127.0.0.1) for 0s
AH01114: HTTP: failed to make connection to backend: 127.0.0.1

This is the config created by openproject installer:

Include /etc/openproject/addons/apache2/includes/server/*.conf

<VirtualHost *:80>
ServerName openproject.domain.tld
DocumentRoot /opt/openproject/public

ProxyRequests off

Include /etc/openproject/addons/apache2/includes/vhost/*.conf

ProxyPass / http://127.0.0.1:6000/ retry=0
ProxyPassReverse / http://127.0.0.1:6000/

Thanks in advance!

Edit: I reinstalled it and during ‘openproject configure’ there is an error:
