I get daily emails from people asking about 430 errors.  430  is  a  message from the server saying "I don't have a part of the
file".
430 means:
1 - The file is too old and has been deleted during regular cleanup.
2  -  The  file is too new and it's not on your server yet. This is for
files under 1 day old when you use search or NZB files.
3 - The file has been removed from the server by the server operators.
US  based  servers  have  to  comply with the DMCA law which means the
servers  have  to  remove  copyrighted  content  at the request of the
copyright owners.  This is the most common issue these days.
There  are several other potential causes but, most of them are pretty
rare.  Some  people use non-US servers as backup because they tend not
to implement #3.
