Answer|Solution:
This may be isolated to just this person’s server config or may be a general ServerPilot issue.
The Plugin Firewall AutoPilot Mode cron is unable to detect the DNS Namesever and is instead generating a php error each time the AutoPilot Mode cron runs. There are several factors involved that could be the root cause for this problem: The Proxy is using the outdated HTTP/1.0 Protocol, Proxy IP addresses are duplicated, etc.
The Primary purpose of the Plugin Firewall AutoPilot Mode cron DNS Nameserver check is to automatically configure/whitelist the Cloudflare domain and IP addresses in the BPS Pro Plugin Firewall.
The most logical solution would be to provide an option setting to disable/turn off the Plugin Firewall AutoPilot Mode cron DNS Nameserver check in cases where there is a server issue/problem. A new option setting to do this will be created in BPS Pro 16.6.
