Ftp is not a built-in class. Which third-party library are you using?

First google result, 450 TLS session of data connection has not resumed - FileZilla Forums[^]

I am not having errors with the FileZilla server. I'm just getting an error in c #. When I run C # on another computer, it still works properly. The application is updating to ftp on computer A. But B is giving error on computer

The error is not specific to FileZilla. You'll need to research the various causes that create that error, like the one in the link.

I've searched the causes, but I can't find any results. I don't know what error there might be about TLS

I'm not sure why you can't find anything. I gave you a link. I got lots of options when I googled the error.
