hi members of this forum,
After logging in to fileZilla I fill in at Host: ftp.pa3cvi.nl
At Username and Password I enter the data that I received from my HostingDiscounter.
Message: server cannot contact my website

In my humble opinion that would be because gate 21 is closed?
That is why I did everything I could to investigate the limiting factor that keeps this gate 21 closed.

I have done the following actions to open the port 21:
- First I opened port 21 of my Ziggo router.
- then opened port 21 in Windows Defender Firewall

A " ping" from my laptop to my website ftp.pa3cvi.nl shows, that this is correct.
A test with the program (URL https://www.grc.com/shieldsup) gives a negative result with: port 21 closed.

I hope someone can help me fix the problem

The server works (although it isn't secure).

You are misunderstanding something - port opening is usually* only required if you are at the server side, but you are at the client side (port 21 is on the other side not under your control). All you need to do is allowing FileZilla to make outgoing connections from and to arbitrary ports, and ensuring your ISP allows FTP (mobile providers tend to block FTP).

*Some data ports would need to be forwarded/opened for allowing the legacy Active (PORT) mode, but that isn't relevant in the context of your question, dealing with the initial connection.
