 * Hi,
 * On specific given addresses the address-checker gives the following error (see
   SCREENSHOT 1: ERROR at [https://imgur.com/a/5ipB49m](https://imgur.com/a/5ipB49m))
 * When I check the same address on the post.nl site it returns correct data, so
   my first guess was wrong. (SCREENSHOT 2 at [https://imgur.com/a/5ipB49m](https://imgur.com/a/5ipB49m))
 * After opening my console.log i noticed the following error (see SCREENSHOT 3 :
   CONSOLE LOG ERROR ttps://imgur.com/a/5ipB49m ). We’ve got a feeling this is causing
   the error.
 * Looking forward for your answer,
 * Dear regards,
    Paul
