Hi, I have a problem with configuration subdomains for nginx. I want to configure domains: [mydomain.com](http://mydomain.com) (port 80) → [http://localhost:8080/](http://localhost:8080/) [www.mydomain.com](http://www.mydomain.com) (port 80) → [http://localhost:8080/](http://localhost:8080/) [subdomain.mydomain.com](http://subdomain.mydomain.com) (port 80) → [http://localhost:8080/subdomain](http://localhost:8080/subdomain) Tomcat listening at 8080 port on localhost. I have application ‘subdomain’ in tomcat webapps folder. ## This is my configuration file: server { listen 80; server\_name [mydomain.com](http://mydomain.com); ``` # Main location location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For ``` $proxy\_add\_x\_forwarded\_for; ``` client_max_body_size 52m; client_body_buffer_size 128k; proxy_connect_timeout 3600; proxy_send_timeout 3600; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_cache_valid 5m; } ``` } server { listen 80; server\_name [www.mydomain.com](http://www.mydomain.com); ``` # Main location location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For ``` $proxy\_add\_x\_forwarded\_for; ``` client_max_body_size 52m; client_body_buffer_size 128k; proxy_connect_timeout 3600; proxy_send_timeout 3600; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_cache_valid 5m; } ``` } server { listen 80; server\_name [subdomain.mydomain.com](http://subdomain.mydomain.com); ``` # Main location location / { proxy_pass http://127.0.0.1:8080/subdomain/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For ``` $proxy\_add\_x\_forwarded\_for; ``` client_max_body_size 52m; client_body_buffer_size 128k; proxy_connect_timeout 3600; proxy_send_timeout 3600; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_cache_valid 5m; } ``` ## } For this configuration http:/www.mydomain.com and http:/mydomain.com working very well, but [subdomain.mydomain.com](http://subdomain.mydomain.com) doesn’t work (there is no response from server). Oh, and [http://mydomain.com/subdomain](http://mydomain.com/subdomain) in browser works well too. I will be grateful for your help.

Hi, Small observation, from your configuration [http://subdomain.mydomain.com](http://subdomain.mydomain.com) Will initiate a request to [http://localhost:8080/subdomain/](http://localhost:8080/subdomain/) and not [http://localhost:8080/subdomain](http://localhost:8080/subdomain) [notice the /] which you said works in the browser. You might want to check that out. Also, you can check out the tomcat’s access logs to see what request you got. ---

@faskiri.devel [http://localhost:8080/subdomain/](http://localhost:8080/subdomain/) is equals to [http://localhost:8080/subdomain](http://localhost:8080/subdomain) Both work the same. In DNS control Panel of my domain I have a ‘A record’ : [subdomain.mydomain.com](http://subdomain.mydomain.com) with IP adress of my VPS server (with nginx and tomcat). It should works… I don’t know what is wrong in my configuration.

Your Apache is not set correctly. Please make sure that the VirtualHost is setup correctly. Basically normal wget is working but if you set the host: header apache rejects the request. I think you have explicity put a VirtualHost domain:8080 changing that to VirtualHost \*:8080 should fix it. In any case, since plain wget also gives you errors, you are better off looking at Apache logs/manual than in nginx. ---

Thank you. I will check tomcat configuration.
