CobianSoft

Hello,
First, thank you for this software, it's awesome and I'm using it for years.

So, about Cobian Reflector, I want to put a backup to an FTP server and I'm using FTP/passive/explicit and TLS 1.2
The problem is when deleting the old backups on the FTP server (I'm keeping 3 full copies) and on deletion the error is (I'm attaching the log also):

Couldn't complete the deletion of files on a remote server: TLS/SSL protection required. (code=504)

With Cobian Backup 11 Gravity everything works great, the deletion through FTP is made with no problem (even on the same server - a Synology NAS where I tested the Cobian Reflector), but that Cobian version has only the TLSv1 and I can't use it on many other servers because of security enforcements.

Keep up the good work!
Cheers!

Hmm... this is a new one. No idea. Need to make some tests.

I would like to report that I've also got that error today with version 0.9.75 BETA.

In my case, the software had no run for days and file to delete were not present (not sure if it's related or not to the error).

What kind of server is this?

I have the same problem. FTP is located on NAS Synology. Programm version - Cobian Reflector 0.9.50 BETA

I had the same problem, it is solved by enabling in synology: Control Panel> File services> FTP Tab> Enable FTP Service (no encryption)
