4 years ago It is not a problem of OTP because otp accept all: https://github.com/opentripplanner/OpenTripPlanner/blob/a499a4f2f3529c53a7859a985b7c1a61033b71dc/src/main/java/org/opentripplanner/standalone/server/CorsFilter.java
I think that the problem is on the hosting machine, maybe there is a proxy in between that rewrite the headers?
I have not problem with this: https://journey.opendatahub.testingmachine.eu/
[ ] investigate to add cors headers in otp response to able access from other domains
[ ] espose it trought ENV var
