Hello
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
TH

Hi @theirman,

Could you please attach a small, simple to follow reproducer so I can verify this issue on my local environment? This will greatly help us identify the issue and provide you with advice

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 ?
