Archive page sometimes not working

Hi all,

I have a very strange situation. I have a custome posttype named “bars”, and a file named “archive-bars.php”.

Sometimes, when i go to https://www.mydomain.com/bars – it gives the search option and says it couldn’t find any content. 5 minutes later it worked again. This is the (yeah – very basic) site:

https://www.iwannagoout.nl/bars/

Thanks!
