      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.

        1. What version of Evok are you running?
        2. 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].
        3. 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;
            	}
            	
            }
