As far as I can see, Google succeeds in everything
Can you tell us exactly what was listed as an error in the google search console?
Bing webmaster tools is “poorly made”
bot is not separated from other MS services (ASN)
and I also believe that the live preview does not directly use BOT
but some other engine (again a different mix IP address) while in fact, the real bot has access to this hosting. You just need to be patient until the bing bot decides to start crawling.
I am also interested in whether you have any custom .htaccess ?
because let’s say if I request any .txt file
your site offers that zero-byte file as a download (non-existent), and that’s not good behavior!
Thank you very much for your detailed and helpful answer. I have fixed the issues you mentioned. Plus in the meantime Google Search Console also tells me that it successfully retrieves the URLs. So indeed, the observation in Bing appears to be an issue on the side of Bing.
The downloads is forced instead of serving the XML file (possible problems with some of the search engines because of this), only when I download that file and open it
I see URLs/links from your sitemaps.
