Your server isn't configured correctly. Your server requires a particular protection level for transfers, yet doesn't impose this requirement on the PROT command used to negotiate said protection level.

Dear Tim

Thanks.

We are able to connect to the same servers
with Filezilla client ver 3.5.2 without getting
the above error.

Do you feel this is a defect with Filezilla ver 3.10.1.1 ?.

Thanks & Regards,
Prashant S Akerkar

Dear Tim

Thanks.

1. What are/is the reason/s we are able
to connect to the same servers in Filezilla
client version 3.5.2 and able to download/upload
files without getting the 534 Protection error?.

2. What are the Server settings to be configured if this is not a defect in Filezilla version 3.10.1.1 ?.

Thanks & Regards,
Prashant S Akerkar

You were not using FTP over TLS in the old version. In the new version, FTP over TLS is automatically used if the server advertises support for it. Unfortunately the server isn't entirely faithful, it isn't correctly configured for FTP over TLS.
