TLS Explicit encryption no longer works

My shared hosting company changed something on the hosting control panel and TLS Explicit encryption no longer works.
Debug log in <invalid hyperlink removed by admin>

Once connected an Error box is displayed.
Message:
"Error listing directory '/domainname.com'

Could not retrieve directory listing
Unable to build data connection: Operation not permitted"

Then I see an empty directory.
When I change directory I get the same message.
I am able to change directories via the Remote/Go To/Open Directory Bookmark menu option but this does not change things.

I posted this but was not logged in at the time.

Thanks for your report.
I have sent you an email with a development version of WinSCP for testing to address you have used to register on this forum.

Got Connection Refused immediately.

I am happy to give you a ftp account if it would make this easier to debug.

Please post or email complete log files from the 4.3.7 and development version for exactly the same session.

This will take me a few days as it is Easter.

I have a similar case to one that another user has reported in the last few days.

The host ftp provider appears to have "changed something"

I am using WinSCP v 4.3.7 and connec using explicit encription over FTP
I am able to authenticate correctly, but the site refuses further dialog. It refuses directory listing, times out on upload and download.

The connection has been working flawlessly for over a year now and the problem first occurred on 3rd April.

Filezilla can connect OK with the new credentials. I use WINSCP to provide automated scripting and hope that this problem can easily resolved

Please let me know if there is further information that would help to diagnose this

Sorry, but the logs are useless, if you edit them.

If send me an email, so I can send you back a development version of WinSCP to test. Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
