we have been getting a lot of errors in our Google Search Console, specifically the Server Conectivity under the Crawl Stats. We then ran a simulated google crawl (using Screaming Frog) of our site, about 400k pages, and 15% of the requests came back with no response. no error/http code, just simply no response. Looking at our web app on Azure we are not seeing these as long requests for 504 errors etc.
Does anyone know of a situation where CF would return no response? or is this getting proxied by CF and the no response is coming from Azure?
Any help appreciated, or if you have skilled to solve this please reach out (would not mind a good contractor to help resolve).
