Both listen 443 ssl http2 reuseport; and listen 443 ssl http2 backlog=4095; specify listening socket options, "reuseport" and "backlog=4095". Socket options are only allowed to be specified once for a given listening socket, and nginx complains as you try to specify time twice. You have to specify both on a single "listen" directive. > Now if I reverse it so backlog=4095 is set in vhost 2 and not vhost 3, then > it works and nginx doesn't complain of errors ?

duplicate listen options for backlog directive for ip:80 and ip:443 pairs ?
I am trying to troubleshoot a duplicate listen options error that only happens on one server and not the other. >From docs at http://nginx.org/en/docs/http/ngx_http_core_module.html backlog listen directive works for each ip:port pair so I should be able to set backlog directive on listen directive once on port 80 and once on port 443. But on one server I am not able to and can't see where the problem is coming from ? How shall I debug this ? --- working --- On working Nginx 1.17.0 server I have 2 nginx vhosts that set backlog properly and have not problems vhost 1 listen 80 default_server backlog=2048 reuseport fastopen=256; vhost 2 listen 443 ssl http2 reuseport backlog=2048; --- not working --- Now on another Nginx 1.17.0 server I have 3 nginx vhosts but nginx restarts complain of duplicate listen options once I add vhost 3 and the error is related for vhost 2's listen directive nginx: [emerg] duplicate listen options for 0.0.0.0:443 in /path/to/vhost2/vhost vhost 1 listen 80 default_server backlog=4095 reuseport fastopen=256; vhost 2 listen 443 ssl http2 reuseport; vhost 3 listen 443 ssl http2 backlog=4095; if i remove vhost 3 backlog=4095 directive there's no error though ? --- working --- Now if I reverse it so backlog=4095 is set in vhost 2 and not vhost 3, then it works and nginx doesn't complain of errors ? No idea why that is the case or if it's a bug ? vhost 2 listen 443 ssl http2 reuseport backlog=4095; vhost 3 listen 443 ssl http2; Posted at Nginx Forum: https://forum.nginx.org/read.php?2,284368,284368#msg-284368 ___ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
