Some nested redirects return "Error code: 522"

Hi! We observed that some of our nested redirects from the old sections now return "Error code: 522".

For example, here is the redirect: [/patrol/finders/advanced](https://github.com/leancodepl/patrol/blob/master/docs/patrol/finders/advanced.mdx)

And when you go to the actual page: https://patrol.leancode.co/patrol/finders/advanced
You can see "Error code: 522".

This redirect works:
https://docs.page/leancodepl/patrol/patrol/finders/advanced -> https://patrol.leancode.co/finders/advanced

So it looks like it doesn't work on custom domains. 🤔
