Tengo problemas para conectarme a un servidor SignalR. Mi configuración inicial en nginx fue
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; }De la documentación de Microsoft, la siguiente es la configuración mínima requerida para habilitar WebSockets en 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] [1]: https://docs.microsoft.com/en-us/aspnet/core/signalr/scale?view=aspnetcore-5.0
