I've changed the router's deployment config quite a bit. At first extending it to 5m, then I grew suspicious that HAProxy settings were even changing and set it to a lower 15s. I found that when adjusting this environment variable the timeout limit does not change. This is especially odd since the generated haproxy.config file appears to have the proper changed values. sh-4.2$ grep -i timeout haproxy.config -n |head -n 10 11: stats timeout 2m 42: timeout connect 5s 45: timeout client 15s 48: timeout server 15s 51: timeout http-request 10s 54: # Long timeout for WebSocket connections. 56: timeout tunnel 1h 218: timeout check 5000ms 259: timeout check 5000ms 300: timeout check 5000ms All the timeout values after line 300 are the same as lines 218, 259, and 300. With this config I am still receiving connection timeouts at 30s. I'm not sure if this is important to note, but the requests that are timing out are HTTP file uploads. > >> I asked in irc with no luck.
