Symptoms
-
Plesk Home page shows the next error:
New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [emerg] a duplicate default server for [2001:db8:f61:a1ff:0:0:0:80]:443 in /etc/nginx/plesk.conf.d/ip_default/example.com.conf:7 nginx: configuration file /etc/nginx/nginx.conf test failed.
-
The following command fails with the same error:
# plesk repair web example.com
-
There is a configuration file with the same IP 2001:db8:f61:a1ff:0:0:0:80 for a non-existing domain:
# grep -Rl "2001:db8:f61:a1ff:0:0:0:80" /etc/nginx/*
/etc/nginx/plesk.conf.d/ip_default/example1.com.conf -
Or the following command shows that there is an orphan configuration file:
# plesk repair web -n
Checking web server configuration. Please waitUnknown file: /etc/nginx/plesk.conf.d/ip_default/example1.com.conf . [ERROR]
Cause
Domain example1.com was removed from Plesk but its configuration file remained.
For this reason, a new configuration file for example.com can not be created.
Resolution
Plesk Obsidian 18.0.35 or higher
Starting from Plesk Obsidian 18.0.35 you can check and remove orphaned configuration files using the Plesk Repair CLI Utility:
# plesk repair web
Plesk Obsidian 18.0.34 or earlier
-
Login to the server via SSH
-
Remove orphaned configuration file:
# rm -rf /etc/nginx/plesk.conf.d/ip_default/example1.com.conf
-
Reconfigure the domain
example.com:# plesk repair web example.com
Note: If the manual domain reconfiguration was successful but Plesk still shows the same error on the Home page - remove the orphaned record about it from the database:
