Resolved Unable regenerate config due to nginx attempting to bind to a non-existing IPv6

[JoeShmoe]

I previously deteled the only IPv6 from my server, I don't intend to use it. However nginx still attempts to use it when regenerating apache/nginx configs for domains
( IPv6 replaced with x:x:x:x:: below)

The IP is no longer present anywhere in Plesk, How can I prevent nginx for trying to use it?
I'm on Plesk Obsidian 18.0.28 Update #3 and Ubuntu 18.04.4

This also prevents me from configuring new websites. Nginx keeps trying to use the non-existent IP.
sysctl -w net.ipv6.ip_nonlocal_bind=1 is a workaround, but I prefer to prevent nginx using that IP.

Please check the following KB article and let me know if it doesn't help - Nginx fails to start: 99: Cannot assign requested address

Thank you,

/usr/local/psa/admin/bin/nginxmng -d
/usr/local/psa/admin/bin/nginxmng -e

worked.
