Consdata blog and presentation playlist not displayed

Recently [Consdata blog](https://github.com/jvm-bloggers/jvm-bloggers/blob/master/src/main/resources/blogs/companies.json#L75) and [Consdata presentation playlist](https://github.com/jvm-bloggers/jvm-bloggers/blob/master/src/main/resources/blogs/presentations.json#L98) have stopped displaying on the website. Both feeds are available, but maybe they are not valid?
