BUG* backup_manager2 not connecting to ftp server

[apartamenti]

I can't create backups to my ftp server! I tried to connect ssh server with ssh it's working but when i tried to connect from CWP panel it's giving login failed. This happened after updating to the new version of CWP server.

* There is a bug in the CWP backup_manager2 module: Instead of saving the value you enter as the FTP password, it automatically generates a placeholder in the format PP + date + time (PP20260514112254). As a result, the FTP server
  returns an "invalid credentials" error.

Also there are errors in console :

I have this bug too.

Nothing yet. Do you solved?

Unfortunately, I haven't been able to find a solution to the problem; since the CWP codes are encrypted with IonCube, I can't see how they work. Only CWP Support can help us with this, but as far as I can tell, they aren't currently working on developing the CWP panel. I've been using CWP Pro for many years, and unfortunately, they're going to lose a lot of users this way!

? Jose just talked about releasing an update possibly this weekend that resolves the new backup issues.

I feel same thing.
CWP is awesome but has a lot of bugs and we don't get this resolved.
We use PRO here too.

Thanks!

I hope that's true, because I'm currently looking for an alternative panel.

Hi!

The SFTP backup does not connect due an error:

Login Failed: Warning: Permanently added 'xxx.xxx.xxx.xxx' (ECDSA) to the list of known hosts. Permission denied, please try again. Received disconnect from xxxx port xxxx:x: too many authentication failures Disconnected from xxxxxx port yyyy

Username and password are correct

Backing up with S3 worked but the /home/tmp_bak/.... does not delete the .tar.gz of username after each backup. I don't let do all backup because im afraid to get a disk full error in home partition disk.

Didn't try other methods.

[Martins-phpbb]

Create the back up in the user panel and it works. The admin panel option still does not work.

Do you still having problems with admin panel sftp scheduled backup?

Hi all!

I can confirm that CWP version 1233 the backups using SFTP are working correctly.

Thank you all!
