Steps to reproduce

Edge supports WebP image format.
Servers do not return WebP files because they do not receive a header (Accept: image/webp) from Edge browser.

Modern browsers do it (like Chrome, Firefox).

Request example (Edge)

GET / HTTP/1.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/18.17763
Host: test.com

Request example (Chrome)

GET / HTTP/1.1
Host: test.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8

Request example (Firefox)

GET / HTTP/1.1
Host: test.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0
