SOLVED: sftp Error: Connection timed out after 20 seconds of inactivity

Error:Connection timed out after 20 seconds of inactivity

This is the message we got when trying to connect to the server using sftp
Status:Connecting to Response:fzSftp started, protocol_version=8 Command:keyfile "somefile.ppk" Command:open "" 22 Error:Connection timed out after 20 seconds of inactivity Error:Could not connect to server

Maximum allowed value for a string variable content in JavaScript

Here is my statement:
I tested by initializing a JavaScript variable, in the browser console, with over 100,000 characters without an error.

My test machine was an I7 with 4GB of RAM.
