I'm having a trouble connecting to a signalR server. My initial setting on nginx was
location /notificationHub/ {
rewrite ^/notificationHub/?(.*) /notificationHub/$1 break;
proxy_pass http://api_beta_server;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
From microsoft documentation the following is the minimum required settings to enable WebSockets on Nginx
# add this at the top of ninx config
map $http_connection $connection_upgrade {
"~*Upgrade" $http_connection;
default keep-alive;
}
# Configure the SignalR Endpoint inside server setting
location /hubroute {
# App server url
proxy_pass http://localhost:5000;
# Configuration for WebSockets
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_cache off;
# WebSockets were implemented after http/1.0
proxy_http_version 1.1;
# Configuration for ServerSentEvents
proxy_buffering off;
# Configuration for LongPolling or if your KeepAliveInterval is longer than 60 seconds
proxy_read_timeout 100s;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
full documentation is on SignalR [documentaion][1]
