Can't get subdomain to work nginx, debian 9

ralphot · Jun 13, 2021

I have this in sites-available for the subdomain (there are two others, https://www.webshooter.se and http://www.webshooter.se):
## For support.webshooter.se subdomain
server {
listen 80;
listen [::]:80;
server_name support.webshooter.se;
root /var/www/support.webshooter.se;
index index.html index.php;
}
and it's linked to sites-enabled.

Have put this in the /etc/hosts file:
127.0.1.1 support.webshooter.se
When I ping locally:
[email protected]:/etc# ping support.webshooter.se
PING support.webshooter.se (127.0.1.1) 56(84) bytes of data.
64 bytes from ws02 (127.0.1.1): icmp_seq=1 ttl=64 time=0.051 ms
64 bytes from ws02 (127.0.1.1): icmp_seq=2 ttl=64 time=0.051 ms

But "Server not found" in browser. http://support.webshooter.se

What do I miss?

You probably forgot to open port 80 in your firewall?

No, because both the other domains works ok on the same server. Try them out. The two others, https://www.webshooter.se and http://www.webshooter.se The first is a test-out system for the old version, the second a slide show for the upcoming, revised version with map. But we need a support function.

From the system where you added the hosts file entry can you try doing the following requests and share the output?

Code:

curl -I support.webshooter.se
curl -I support.webshooter.se/index.php
curl -I support.webshooter.se/index.html

Will do.

I have also another "subdomain" on the same server:
[email protected]:/etc# curl -I http://www.webshooter.se/index.html
HTTP/1.1 200 OK
Server: nginx/1.18.0 (Ubuntu)

This works and the difference from the others is: X-Frame-Options: SAMEORIGIN

I have a index.php no .html in the support page.

Looking at this output the webserver isn't the problem:
1. You get an OK/200 back which is good.
2. You also get an OK/200 back.
3. You get an 404/Not found back since the file doesn't exist but it is a response from the webserver so it's working as expected.

I think the problem is somewhere else, also check the log file of the subdomain that may give you some more information.

log file of the subdomain? Where can I find that? What I have in /var/log/nginx is: 0 Jun 15 06:25 webshooter.se-error.log empty and nothin comes there if I update support.webshooter.se. Strange...

ralphot · Jun 15, 2021

Sorry, han no error enabled in the sites-enable file for the support-page. Have that now but no errors occur when updating page. Very odd.

What does: X-Frame-Options: SAMEORIGIN means that comes with the working subdomain?

That has nothing to do with the problem since that's just a header, that's usually defined in the virtualhost of the subdomain.

Usually you define a separate log file per virtualhost or subdomain, if you haven't done than that it probably goes all in the same log file.

Is support.webshooter.se on the same server as the other domain you mentioned, that way I can try adding it to my hosts file.

Code:

www.webshooter.se.    3600    IN    A    194.54.164.156

ralphot · Jun 15, 2021

Tried that but www.webshooter.se works? tried with:
support.webshooter.se. 3600 IN A 194.54.164.156
No success... restarted nginx each time of course

ralphot · Jun 15, 2021

Is it a DNS problem? Don't think I have a DNS server in the system

ralphot · Jun 15, 2021

I have a resolv.conf contains:
nameserver 127.0.0.53
options edns0
Thank you for taking time to help me...

f33dm3bits · Jun 15, 2021

If I add this to my hosts file.

Code:

194.54.164.156 support.webshooter.se

And then the page loads.

ralphot · Jun 15, 2021

YES, thats the output of the .php file!

194.54.164.156 support.webshooter.se

I tried to put that in my hosts file but no success?

ralphot · Jun 15, 2021

I put that in my hosts file with same result, but it have to work on the server, all users can not do that?
