Disabling Faststart killed my server

[Sicilian]

As the title, disabling Faststart killed my server.

Was getting this error: -

csf: FASTSTART loading Packet Filter (IPv4)
Error: FASTTART: (Packet Filter IPv4) [] [iptables-restore: line 14 failed]. Try restarting csf with FASTSTART disabled, at line 3777

So done this, found on support geek: -

Edit csf config file located at /etc/csf/csf.conf and disable FASTSTART by editing FASTSTART = "1" to
FASTSTART = "0".

Once the change is made restart csf by running csf -r, csf should be running fine now.

I then used Winscp to edit csf.conf, all I did was disable Faststart, 1 to 0.

Then restart csf -r, bam! Some scrolling text about IP tables and died.

Rebooted from server manager, reboot fine, but zero access, ftp, ssh, nothing.

Checked access via 4G mobile incase CSF has blacklist my IP, again, nothing.

Server is now in rescue mode awaiting my server admin to take a look.

Any ideas anyone?

Same to me, afterwards, I managed to access the server, however the CSF seems was not working at all.
