OSRM server HTTP request failed:undefined

[shin0859]

This is my first question. My name is shin2.

I'm trying to set up an OSMR server on my home web server using the following site as a reference, but I'm having trouble with an error at the final stage. If you have any good advice, please let me know. PS I'm not good at English

【Web Site Error】 https://signpost.mydns.jp/mapNavi01/naviplan01.html Routing error Calculating the route caused an error Technical description folloes HTTP request failed:undefined

Is this error related? window.XMLHttpRequest === 'undefined' if (typeof window.XMLHttpRequest === 'undefined') { return callback(Error('Browser not supported')); } I don't have the knowledge to solve this myself, so can someone tell me how to fix it?
