I also still can't ping when both servers are in the csf.allow and csf.deny files. ICMP_IN = "1" ICMP_IN_RATE = "1/s" (al...

Edit the /etc/csf/csf.conf and set the CC_OLDGEOLITE to 0. Restart csf.

firewalld runs independent of csf/lfd, you shouldn't need it.

Is it a standard installation or DirectAdmin etc.? What is in the /etc/csf/csf.deny file?

I believe it's not blocked because of csf (IP match in csf.allow, block may not work) but because of incorrect authentication data (password, protocol, certificate, cipher suite, etc.) Check your auth logs.
