Symptoms

• On the Plesk homepage, you see the following error:
• New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [emerg] bind() to 10.9.23.65:80 failed (99: Cannot assign requested address) nginx: configuration file /etc/nginx/nginx.conf test failed . The error message containing the detailed error descriptions was sent to you by e-mail. Please resolve the issues and click here to generate broken configuration files once again or here to generate all configuration files.
• Nginx cannot start:

  [emerg] bind() to 10.9.23.65:80 failed (99: Cannot assign requested address) ;
  

Cause

• IP was removed from server directly but was not removed from Plesk
• IP of the server was changed directly on the server. Plesk do not update configuration automatically.

Resolution

1. Sync Plesk database and IP addresses on the server:

   # /usr/local/psa/bin/reconfigurator --autoconfigure
   

   Please pay attention to the output of the first command. It may contain the same IP address listed in several sections and also some IP addresses listed under ‘`Database`’ but not listed under `’Actual’`:

   [root@srv ~]# /usr/local/psa/bin/reconfigurator –autoconfigure
   Database: [<1.2.3.4>, <5.6.7.8>, <9.1.2.2>, <8.1.2.3>, <7.1.2.3>, <6.1.2.3>, <0000:a0a0:0000:a0:225:00a0:0a00:0a00]
   Actual: <1.2.3.4>, <5.6.7.8>, <9.1.2.2>, <8.1.2.3>, <7.1.2.3>, <6.1.2.3>]
   Removed IPs: [] [<0000:a0a0:0000:a0:225:00a0:0a00:0a00>]
   Added IPs: [] []
   Mapping: {}
   Old not remapped: [<0000:a0a0:0000:a0:225:00a0:0a00:0a00>]
   New not used: []

   The above case indicates that Ipv6 address 0000:a0a0:0000:a0:225:00a0:0a00:0a00 was removed directly from the server interface.

2. You can use the following steps to repair the IP address:a. Access Tools & Settings > IP Addressesb. If there is an IP address marked with an exclamation point and a broken state, click the repair link.

   c. If there are no broken IP addresses, click re-read. Now, these broken addresses should be revealed and repaired as per p.2

3. Now reconfigure web-server:

   # /usr/local/psa/admin/sbin/httpdmng --reconfigure-all
   

4. Start nginx:

   # /etc/init.d/nginx restart
