On-Premise: Not working - Test Workflow

Questions
1

Hi All,

I’m using latest version for on-promise n8n (v 1.74.3) installed via docker where I’m having the following issue:

I can’t really debug and test flows as in test more, where its saying “Listen for test event” it does not display requests.

Execute previous nodes in Editor are also empty No input data yet while all requests are logged properly under Executions tab.

What would be the way to resolve it?

Thanks

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @n8ntb,

Welcome to the community :raised_hands:

Is it safe to assume that you are using nginx as your reverse proxy of choice?

it is proxy over apache — it is set as following, and I feel the issue is there:

<VirtualHost *:443> 
 
	ServerAdmin webmaster@domain
	DocumentRoot "/home/n8n"
	#RemoteIPHeader CF-Connecting-IP
	
	ServerName n8n.domain
	ServerAlias n8n-test.domain

	ProxyRequests       Off
	ProxyPreserveHost    On

	ErrorLog  ${APACHE_LOG_DIR}/error.n8n.log
	CustomLog ${APACHE_LOG_DIR}/access.n8n.log combined

	<Proxy *>
		Order allow,deny
		Allow from all
	</Proxy>

	ProxyPass / http://127.0.0.1:5678/
	ProxyPassReverse / http://n8n.domain

	RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}

	RewriteCond %{HTTP:Upgrade} websocket [NC]
	RewriteCond %{HTTP:Connection} upgrade [NC]
	RewriteRule ^/?(.*) "ws://127.0.0.1:5678/$1" [P,L]
</VirtualHost>

Any thoughts?

Hey @n8ntb,

The issue will be with the websockets, I am not overly familiar with the Apache configuration but I do know that the below works.

<VirtualHost *:80>
        ServerName n8n.yourdomain.tld

        RewriteEngine On
        RewriteCond %{HTTP:Upgrade} =websocket [NC]
        RewriteRule /(.*)           ws://172.17.0.1:5678/$1 [P,L]
        RewriteCond %{HTTP:Upgrade} !=websocket [NC]
        RewriteRule /(.*)           http://172.17.0.1:5678/$1 [P,L]
        ProxyPassReverse /          http://n8n.yourdomain.tld
</VirtualHost>

Looking at your config I would probably start with something like…

<VirtualHost *:443>
        ServerName n8n.domain
        ServerAlias n8n-test.domain
        DocumentRoot "/home/n8n"

        RewriteEngine On
        RewriteCond %{HTTP:Upgrade} =websocket [NC]
        RewriteRule /(.*)           ws://127.0.0.1:5678/$1 [P,L]
        RewriteCond %{HTTP:Upgrade} !=websocket [NC]
        RewriteRule /(.*)           http://127.0.0.1:5678/$1 [P,L]
        ProxyPassReverse /          http://n8n.domain
</VirtualHost>
