Bing Index Problem 301 Moved Permanently. openresty

Dear Forum Friends,

How are you doing?

This is Jerome from China, recently I met a big SEO Sitemap submit problem.

I have submitted my webflow site to for so many times, but bing webmaster tool show the following info.: We were not able to connect to the DNS (Domain Name Server) for this URL. Please review with your technical team, web hosting company.

And when I search on, it shows:
301 Moved Permanently. openresty

But I have not setted the 301 function on webflow.

Read-only link:Webflow - Maytown Led Light

When I use url inspection tool to check,it shows:
Content-Length : 166
Content-Type : text/html
Location :
Server : openresty

301 Moved Permanently

Thank you

Best Regards
