Thanks for sharing!
Since one of the versions (a couple of years ago), the official support for TLS less than 1.2 has been dropped:

Same here. One file upload is good, sibling file - error that described above.

PhpStorm 2023.2
Build #PS-232.8660.205, built on July 28, 2023

Fixed this way:

1. Copy contents and name of file
2. Delete local file
3. Create new local file, put contents, change name
4. Upload new local file
5. No error

For anyone who is dealing with this issue: in my case it turned out to be that I had reached the server-side disk quota. Especially if smaller files are succeeding (which was the case for me as well), this might be the culprit.

That issue still there, I can upload one or 2 files, but after that I get all sorts of errors, however that only happens on Windows, when I'm on my Linux distro (Arch) I have no error except for the JavaSDK version, but that is another story…
