nginx not running

juntiedt

I installed evok on rpi4 with buster. One wire, websocket runs ok but I am unable to run the control panel due to nginx problems.

Any idea how to fix it without reinstalling evok?

Hello @juntiedt,

it seems that the evok site configuration file has not a valid content.

What version of Evok are you running?
Did you follow the installation guide on Evok github page (section Legacy installation process using a shell script)? Note that the .deb package installation is not available for Unipi1.1[lite].
Can you send us the content of your /etc/nginx/sites-enabled/evok file?

OK, now it is a bit clearer. You probably did not insert TCP port while you have been asked for it during the installation process. Default values within the file are:

upstream evok {
        server localhost:8080;
}

server {
	listen 80 default_server;
	server_name  _;

	#ssl on;
	#ssl_certificate      /etc/nginx/democert.pem;
	#ssl_certificate_key  /etc/nginx/democert.key;

	#access_log  /var/log/evok.access.log;
	access_log  off;
	root /var/www/evok;

	location / {
	    index index.html;	    
	}
	
	location /favicon.ico {
		alias /var/www/evok/favicon.ico;
	}

	location /ws {
		proxy_pass http://evok;
		proxy_set_header Host $host:$server_port;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "upgrade";
		proxy_buffering off;
		proxy_cache off;
		proxy_read_timeout 180;
	}

	location /rest {
		proxy_pass http://evok;
		proxy_set_header Host      $host:$server_port;
	}
	
	location /json {
		proxy_pass http://evok;
		proxy_set_header Host      $host:$server_port;
	}
	location /bulk {
		proxy_pass http://evok;
		proxy_set_header Host	$host:$server_port;
	}
	location /rpc {
		proxy_pass http://evok;
		proxy_set_header Host	$host:$server_port;
	}
	
}
