[QUESTION] Please help (Error: The remote server returned an error: (400) Bad Request.)

[m0rph3us96]

There is an error when I enter the code here.
I want to add that our SSH port is changed into 222 for security purposes. Hope this can help :)
Here is a screenshot below.

And also, is there a way to make a bulk backup (set of IPs). I have so many Pfsense servers here.
