Hi JazzIT,

Based from the messages, something is adding headers that Traveler doesn’t know about. For security reasons, those requests are being rejected. Either they are being rejected properly or something is adding the extra headers to the request and they need to be allowed by adding a regex value as that ini’s value so that they are allowed. But the default is secure (not allowed), so you must look at it and decide if you want to allow those headers or not. If you do want to allow them, set the regex to allow them.

Kindly make sure the requests are correct and are not properly detecting something that shouldn’t be going on. You can set some FINEST logging for Traveler to get more details on the requests or enable the HTTP thread logs to see the full HTTP request details (headers) if you don’t have some other way to get that information from HTTP using other logging/tracing.

You can refer to this documentation.

I hope this helps. Thanks!
