Question Websites do not respond on port 80 but respond properly on port 7080

Raj

Raj

New Pleskian
According to this https://kb.plesk.com/en/119053 post the cause of this is: "The Nginx process was stopped on server." But in my case nginx is running properly.
Nginx is running in port 80 and 443.
Apache is running in 7080 and 7081.

Product version: Plesk Onyx 17.0.17
OS version: Ubuntu 14.04

Hi Raj,

looks like we both maybe have the same problems.

Can you take a look at your proxy_error_log and watch if there is something like this:

Code: 
[error] 31323#0: *1 openat() "/var/www/vhosts/candypanda.io/httpdocs/favicon.ico" failed (13: Permission denied), client: 109.91.38.234, server: candypanda.io, request: "GET /favicon.ico HTTP/1.1", upstream: "https://62.141.41.27:7081/favicon.ico", host: "candypanda.io", referrer: "https://candypanda.io/"
 
Check, at least, that port 80 is not firewalled.
What is output of command

# lsof -i tcp:80

on your Plesk server?
 
@IgorG
output of lsof -i tcp:80

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 24823 root 9u IPv4 63536 0t0 TCP philippelebac.cn:http (LISTEN)
nginx 24824 nginx 9u IPv4 63536 0t0 TCP philippelebac.cn:http (LISTEN)

FYI philippelebac.cn was hosted earlier in this server due to this problem i have moved it to another server.
Currenlty i have hosted plbht.ml website here for testing purpose.

Check that site is accessible from your internal network at least, from different places. Check your network configuration, routing, firewalls, etc. Check that other sites on this Plesk server can be opened.
Once again, if you talk about http://philippelebac.cn site - it is accessible from my workstation.
 
Any website hosting in this server is not working, having problem in all. I have tried another locations also. As i had already told that due to this server problem i have hosted philippelebac.cn in another server. thats why you and i am able to open that.
currently i have hosted plbht.ml in this server which is not opening in port 80 but opening in port 7080.
 
#netstat -ntlp | grep :80 output
tcp 0 0 222.73.236.48:80 0.0.0.0:* LISTEN 10345/nginx
 
I see that there is 400 Bad Request nginx error when I connect to port 80 of plbht.ml through telnet:


# telnet plbht.ml 80
Trying 222.73.236.48...
Connected to plbht.ml.
Escape character is '^]'.
quit
HTTP/1.1 400 Bad Request
Server: nginx
Date: Tue, 22 Nov 2016 09:33:48 GMT
Content-Type: text/html
Content-Length: 166

Looks like there is some kind of nginx customization/redirects/something else. Try to disable nginx temporary with

# /usr/local/psa/admin/sbin/nginxmng -d

and check result.
 
disabled nginx
restarted apache2

#netstat -ntlp | grep :80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 11347/apache2

still not able to browse
 
Very strange error now:

# telnet plbht.ml 80
Trying 222.73.236.48...
Connected to plbht.ml.
Escape character is '^]'.
quit

Look at description - http://servererrorcodes.com/501-not-implemented/

Have you tried to run

# plesk repair web -y

at least?
 
yes i have done # plesk repair web -y and also # plesk repair all -y
still having same problem

nginx is still disabled
 
# telnet plbht.ml 80

output of my telnet is also same from server ssh
 
Hi Raj,

... apart from the "501" - error, pls. note, that your standard Plesk - certificate is not even valid anymore: "Fri, 23 Sep 2016 10:16:12 UTC (expired 1 month and 29 days ago) EXPIRED". Consider to change the default certificate, according to:


Pls. note as well, that your reverse DNS - check of your IP "222.73.236.48" results in errors. Pls. see for example => https://www.dnswatch.info/dns/dnslookup?la=en&host=222.73.236.48&submit=Resolve / => http://viewdns.info/reversedns/?ip=222.73.236.48
