New version FileZilla_3.56.0_win64 causes GnuTLS error

[Chris Stivers]

Connection to host works fine with FileZilla_3.52.2_win64. On installation of 3.56.0 connection fails with "GnuTLS error -8: A packet with illegal or unsupported version was received."

Reinstalling 3.52.2 restores ability to connect.

TLS error when connecting

[Tim Kosse]

Contact your server administrator or server hosting provider to have the server updated, it uses an antique and insecure TLS version one must no longer use.

See ​https://datatracker.ietf.org/doc/html/rfc8996

I understant this argue, whatever this is not imho correct answear.

The problem has only Filezilla. Other products (like winscp), has not problem. I have no chance to change my hosting. Only what i can is use pure FTP.

So this is way to be less secure!

Or to use old version Fillezila (still less secure). Or any other client (more secure...).

So I'm not sure that this decision is the best...

[Tim Kosse]

WinSCP is insecure, it implements neither opportunistic FTP over TLS nor RFC 8996.

Tim, I understand. But maybe is insecure, but if I want use Fillezila, is more secure (bec. I must use pure FTP, if I need connect). Some times is solution not black and white...

Maybe there can be warning - "your FTP over TLS is not byl RFC", are you sure, you want connetc?
Or there can be possibility (checkbox), which can use less secure connection (but more secure then pure FTP).

I wrote to hosting, but i thing, there is no way to change it. I have no force to change hosting now.
