PHP Storm and making FTP connections with SSL (FTPS)

If you’re having issues connecting to a server via FTPS in phpStorm I found that the magic combination for PHP Storm and FTP-SSL connections is…

• Type: FTPS
• SSL: Explicit
• Passive Mode: On
• Protected data channel:

In particular the Protected data channel was set to “PRTO C” by default on my install and it was that causing the bother.

Error Message:

[23/11/2015 12:13] Failed to transfer file 'C:\web\htdocs\
•••••\••••••••••••\test.txt': cant open output connection for
file "ftps://•••.•••.•••.•••/test.txt". Reason: "500 I won't 
open a connection to 192.•••.•••.••• (only to 81.•••.•••.•••)".
