I am having this same issue and I posted a thread about it too. I can’t seem to find a solution though my robots.txt seems fine.
Here is a copy of my post:
Using the Yoast plugin I created a sitemap and then attempted to input it in the Google Search Console. I have been trying different ways of doing this for the past several weeks and I cannot get Google to fetch the sitemap.
In the sitemap section on the Google page it reads sitemap type as “unknown” and the status reads as “couldn’t fetch.”
I am using Yoast 9.5 and all my other plugins are up to date. My sitemap is located here: https://rjoyphoto.com/sitemap_index.xml
I have been consistent in using https so that should not be an issue either. In the older version of the Google Search Console it reads “pending” as the submission status for the sitemap. I am able to “fetch as Google” and do everything else except for upload the actual site map and the last time Google crawled my site was on 25 January, before it was even live.
Can anyone help???
