Outgoing PASV FTP blocked on new server, but was working on my old server

[WEHA]

I installed a new Centos 7 server, the same as my old server.
On my old server I could connect to FTP servers with PASV no problem.
But on my new server it blocks the connection.
SPI is on, Connection tracking is on.
Incoming FTP connections with PASV work fine (without the hole).
How do I get the outgoing ftp servers to work? (without whitelisting them)

thanks!

I noticed my new server runs on Kernel 4.18.0-147, even though they should be the same.
Both are Centos 7.8 & Cloudlinux and update automatically...
So the old server has 3.10.0-962.

I suppose maybe the outgoing connection tracking on 4.18 is not working?

So, incoming does not work either...
I assumed the connection tracking was working but my IP was whitelisted so it worked nonetheless.
