The default TCP port for FTP connection is port 21. Sometimes the local Internet Service Provider blocks this port and this will result in FTP connection issues.
Here's how to check whether your ISP has blocked port 21 depending on your OS:
1. Check port 21 with a Windows OS:
Click on the Start menu button, usually located on the left low corner of the screen. There is a tab called "Run". You have to click on it, in order to proceed further. You will notice the appearance of a new small window on the screen. In the text field of this window you need to type "cmd" and then press the "Enter" key. Another window will open. It is the so called "MS-DOS prompt" or "command prompt". Just type the following command in the command prompt window and press "Enter":
telnet my-domain-name.com 21
2. Check port 21 with Apple/Mac:
Each Mac OS is delivered with a preinstalled terminal emulator. The terminal is a tool which allows you to execute commands from the command line. Usually, the terminal is located under your Mac HD -> "Applications" directory -> Utilities sub-directory. When the window opens, you will see a command line with a flashing cursor on it so you can start typing right away. Just type the following command and press "Enter":
telnet my-domain-name.com 21
3. Check port 21 with Linux:
Open your favorite terminal emulator and execute the following command in order to telnet your website:
telnet my-domain-name.com 21
Results from the 21 port check
If the test is successful, you should receive a message like this:

Website Down: I cannot access my website, site errors, site slow, hacked websites etc.
HTTP Error 403 - Forbidden
Generally. the HTTP error 403 - Forbidden means that access to the file/folder you are trying to open has been denied, either on purpose or due to a bad configuration.
If you suspect that only your access is blocked, try a web proxy to hide your identity.
