Lots of 404s

Hi Frank,

First of all thanks for the awesome work with autoptimize. It’s a great plugin!

I would like to ask for your help with an issue I recently encountered.
There are a lot of 404s and they are referrals from my very website.

I use autoptimize with wp-rocket and async javascript pro.
Any direction would be greatly appreciated.
Here are a few examples of the 404s:
