Greetings, As the title says, Unraid behind an NGINX reverse proxy initially works, but will become unresponsive in ~30-45 seconds. * This problem may occur on older versions, I just started using Unraid again * I am using NGINX reverse proxy function * NGINX lives on a system that is external to Unraid, but internal to my network * Neither NGINX nor Unraid have exposure to the Internet * DNS resolution is happening internally, no external influence * The connection (unraid.domain.com) works fine - websockets enabled. But after 30-45 seconds or so, the websockets stop updating. The websocket stuff - graphs, drive rw - freezes in place * I use many websocket-based services behind this reverse proxy, Unraid is the only one with issues * Affects Firefox and Chrome * Affects Windows and Linux When this occurs, I can still navigate using the menu buttons. And when I do click one, everything works fine again for about 30-45 more seconds before the websockets die again. My NGINX reverse proxy configuration is as follows: server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name unraid.domain.com; include ./conf.d/domain.com.sslsettings; access_log /var/log/nginx/unraid-access.log; error_log /var/log/nginx/unraid-error.log; location / { proxy_pass https://192.168.10.40:443; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_read_timeout 300s; proxy_send_timeout 300s; proxy_connect_timeout 75s; proxy_buffering off; } } I did try disabling HTTPS, but this didn't change anything. I think the SSL errors are a red herring: unraid-error.log: 2025/06/18 20:50:14 [crit] 4090#4090: 1259 SSL_do_handshake() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while SSL handshaking, client: 192.168.10.10, server: 0.0.0.0:443 2025/06/18 20:50:14 [crit] 4089#4089: 1260 SSL_do_handshake() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while SSL handshaking, client: 192.168.10.10, server: 0.0.0.0:443 2025/06/18 22:04:22 [crit] 4089#4089: 3583 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while processing HTTP/2 connection, client: 192.168.10.10, server: 0.0.0.0:443 2025/06/18 22:04:38 [crit] 4090#4090: 3688 SSL_do_handshake() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while SSL handshaking, client: 192.168.10.10, server: 0.0.0.0:443 2025/06/18 22:05:11 [crit] 4090#4090: 3584 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while processing HTTP/2 connection, client: 192.168.10.10, server: 0.0.0.0:443 2025/06/18 22:05:16 [crit] 4090#4090: 3702 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while proxying upgraded connection, client: 192.168.10.10, server: unraid.domain.com, request: "GET /sub/cpuload,update1,update2,update3 HTTP/1.1", upstream: "https://192.168.10.40:443/sub/cpuload,update1,update2,update3", host: "unraid.domain.com" 2025/06/18 22:05:16 [crit] 4089#4089: 3695 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while proxying upgraded connection, client: 192.168.10.10, server: unraid.domain.com, request: "GET /sub/wlan0 HTTP/1.1", upstream: "https://192.168.10.40:443/sub/wlan0", host: "unraid.domain.com" 2025/06/18 22:05:16 [crit] 4090#4090: 3705 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while proxying upgraded connection, client: 192.168.10.10, server: unraid.domain.com, request: "GET /sub/session,var,notify HTTP/1.1", upstream: "https://192.168.10.40:443/sub/session,var,notify", host: "unraid.domain.com" 2025/06/18 22:05:16 [crit] 4090#4090: *3752 SSL_read() failed (SSL: error:0A000126:SSL routines::unexpected eof while reading) while processing HTTP/2 connection, client: 192.168.10.10, server: 0.0.0.0:443 Anyone running a similar setup that has working websockets?
