Unable to access SSL/TLS Certificates domain's option in Plesk with the following error:
Could not get Mozilla TLS config: cURL error 6 could not resolve host: statics.tls.security.mozilla.org; Unknown error (see https://curl.haxx.se/libcurl/c/libcurl-errors.html).
Name resolution issue.
statics.tls.security.mozilla.org could not be resolved from Plesk server.
Connect to the server via SSH.
Add Google nameserver to
# echo "nameserver 220.127.116.11" >> /etc/resolv.conf
If the issue persists re-enable local firewall rules and restart Plesk services:
# systemctl restart sw-engine && systemctl restart sw-cp-server
Note: If the server is running with
systemd-resolved adjust the networking configuration manually or contact the hosting provider for assistance.
