please don’t post your API key as other people will be able to use it (also is a hint in the topic placeholder which you should read before posting)
Regarding your problem, please provide an exact full query and response with headers included.
Normally the response should include the
access-control-allow-origin: * header:
HTTP/2 200 OK
date: Tue, 18 May 2021 12:28:46 GMT
content-type: application/json; charset=utf-8
access-control-allow-methods: GET, OPTIONS
access-control-allow-headers: Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Authorization, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers
access-control-expose-headers: x-ratelimit-remaining, x-ratelimit-reset, x-ratelimit-limit
My guess is, that you run into the minutely request limit of 100 requests (Plans | Openrouteservice which you should adhere to) and the error response is not including the header.
