Issue IPv6 / nginx error

[leonelias]

Hello everyone.
I added a few IPv6 addresses via Plesk and for every IPv6 address added I received this email with this error.

Unable to generate the web server configuration file on the host <my-hostname> because of the following errors:

Template_Exception: nginx: [emerg] bind() to [2a03:XXXX:XX:716::4]:443 failed (99: Cannot assign requested address)
nginx: configuration file /etc/nginx/nginx.conf test failed

file: /opt/psa/admin/plib/Template/Writer/Webserver/Abstract.php
line: 75
code: 0

Please resolve the errors in web server configuration templates and generate the file again.

I hope you can help me and say why every IPv6 address is added! (If I remove it and put it back on, the same thing happens.)

best regards
Leon

interesting do you use custom templates settings? it sounds ike unsynced IP address between Plesk and OS. If you go in the Plesk panel > tools & settings > IP addresses are the IPV6 addresses available or any issue?
