Hi All, Newbie question. I posted this on Stack Overflow but haven't gotten any replies yet. https://stackoverflow.com/questions/63391424/why-do-i-get-connection-timeout-on-ssl-even-though-nginx-is-listening-and-firewa
Most/many visitors to my site https://example.org get a connection timeout. Some visitors get through, possibly ones redirected from http://example.org or those who've previously visited the site. I'm trying to determine if this is a firewall issue or an nginx configuration issue. Firewall I'm using UFW as a firewall, which has the following rules: To Action From -- ------ ---- SSH ALLOW Anywhere Nginx Full ALLOW Anywhere 80/tcp ALLOW Anywhere 443/tcp ALLOW Anywhere SSH (v6) ALLOW Anywhere (v6) Nginx Full (v6) ALLOW Anywhere (v6) 80/tcp (v6) ALLOW Anywhere (v6) 443/tcp (v6) ALLOW Anywhere (v6) I could give some relevant rules from iptables if anyone needs that, but I'd need some direction on what to look for. For sudo netstat -anop | grep LISTEN | grep ':443' I get tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 120907/nginx: worke off (0.00/0/0) tcp6 0 0 :::443 :::* LISTEN 120907/nginx: worke off (0.00/0/0) Not sure what "worke off" means. nginx It's a virtual host with the server name myservername.com which serves up two websites, example.org and example.com/directory. Example.org points to a docker container running eXist-db. Example.com/directory is serving up a directory on localhost:8080 proxied from another server where example.com lives. Example.com/directory is running smoothly on https when I access it in the browser -- I presume this is because it actually talks to the example.com host over http. Example.org and myservername.com both have certs from let's encrypt generated by certbot. When I try nmap from my local machine I get some results I can't explain. Notice the discrepancy between ports 80 and ports 443 and between IPv4 and IPv6 $ nmap -A -T4 -p443 example.org 443/tcp filtered https $ nmap -A -T4 -p443 my.server.ip.address 443/tcp filtered https $ nmap -A -T4 -p443 -6 my:server:ip::v6:address 443/tcp open ssl/http nginx 1.10.3 $ nmap -A -T4 -p80 example.org 80/tcp open http nginx 1.10.3 $ nmap -A -T4 -p80 my.server.ip.address 80/tcp open http nginx 1.10.3 My nginx.conf is user www-data; worker_processes auto; pid /run/nginx.pid; include /etc/nginx/modules-enabled/*.conf; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## client_max_body_size 50M; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # SSL Settings ## ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE ssl_prefer_server_ciphers on; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } and my nginx server blocks: server { listen 80 default_server; listen [::]:80 default_server; server_name _ myservername.com; return 301 https://myservername.com$request_uri; } server { # SSL configuration # listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name _ myservername.com; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://localhost:8080; } ssl_certificate /etc/letsencrypt/live/myservername.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/myservername.com/privkey.pem; } server { listen 80; listen [::]:80; server_name example.com www.example.com; gzip off; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://localhost:8080; } } server { listen 80; listen [::]:80; server_name example.org www.example.org; return 301 https://example.org$request_uri; } server { # SSL configuration # listen 443 ssl; listen [::]:443 ssl; server_name example.org www.example.org; gzip off; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://docker.container.ip.address:port/exist/apps/example/; } location /workshop2020/ { return 302 http://example.org/forum2020/; } location /exist/apps/example/ { rewrite ^/exist/apps/example/(.*)$ /$1; } ssl_certificate /etc/letsencrypt/live/example.org/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/example.org/privkey.pem; # managed by Certbot } Very grateful for any help!!
