Thanks for the quick answer,
Indeed the issue is related to the way we consider canonical.
We crawl the Prime url to be sure to crawl the correct version (if for example you have multiple branches configured). And we ignore all everything that does not begin with
Your have an absolute canonical which is pointing to your main domain and so we can not crawl it.
The temporary fix is to use relative canonical, which is supported by the standard
<link rel="canonical" href="https://www.andreavaghi.dev/">
<link rel="canonical" href="/">
But as the github issue suggest, we are currently thinking about some kind of hostname aliases so we can more scenario out of the box.
Hope this helps,
