Error "HTTP/1.1 417 Expectation Failed" when calling webservices

We have a problem with Payara version 5.2022.2.

On some requests, we get an “HTTP/1.1 417 Expectation Failed” error while on most others we have no problem

Have you ever encountered this problem? If so, how do you solve it?

Thanks in advance

Hello
When we submit a resquest that take longer than 30s to respond, Payara send 417 to the reverse proxy and the request failed.

When reading on internet, some site mentionned this can be caused by the expect100continue option. How to deactivate this option in Payara ?
