Unable to pin using pin it widget

I have attempted pinning from both the pin it widget and using a pin it on my address bar on safari but I keep getting this code

Parameter ‘source_url’ (value https://69.89.31.112/~rawgrap1/blog/) is not a valid URL format.

I have no idea how to pin anything on my site! Any help is appreciated!
