I have been using WinSCP for some years now (2-3) to upload files to my hosted website.
Settings: FTP, Encryption TLS/SSL Explicit; Host name, Port# and Username already entered.
When I connect, I only input the password and then press the Login button to connect.
So far, no problems.
I installed the software (a) manually (downloaded+installation) from website and, more recently (today), (b) downloaded from Windows Store and installed by Windows 10.
BOTH versions display the following error (starting from 30 mins ago) when I try to upload files:
"Copying files to remote side failed.
Disk full - please upload later".
I switched to uploading my files using the (less user friendly) utility of my Web Hosting Provider and it works flawless.
What is the problem ?
