I already sent a message through the support form (https://shop.nusphere.com/customer/support.php) 4 weeks ago and didn't got any reply yet.

Content oy my message from 29th of october 2024:

I cannot upload (overwrite) files already remotly existing by SFTP to the server of my hoster.

Every try to upload a file that exists, following error is shown in PhpED:
"Attempt to run an operation on closed connection"

This problem only exists in PhpED. As workaround I have to upload the files with WinSCP - without any errors, also using SFTP connection with same credentials.

Feel free to test by yourself with the following login data:

login data provided in support ticket message

Steps to reproduce:

1. Create file locally
2. Upload file
3. Change file locally
4. Upload changed file
5. Error message appears

Forgot to mention.... FTP is also not working.
Error message for FTP on upload or download:

Next one....: also happens for downloading in 50% of the cases.
And if you do a "Publish -> Download file" and the error occurs, the local file end up empty.
