Why does PhpStorm send an empty file to the server?

Question

phpstorm

I open the file via Remote Host, change it and send it to the server. After he allegedly sent, I go to the server, open the file with another editor and it turns out that the file is empty. What could it be and how to fix it.
PS In PhpStorm the file remains with all the data
