Hey Leo0731
Apologies for my delay in replying. We've reached and breached the limits of my knowledge in this regard. I mean, we could walk through the ReadyAPI help together - trying to find the issue - but as it worked before - there's just nothing tangible to try and focus on to work out what the problem was. All your config is perfect, otherwise it wouldn't have worked in the first place.
I have 1 suggestion. As it was working fine before and it appears that no changes have actually been made, have you tried re-creating the request from scratch?
I had a similar issue several years ago - when there was no corruption (that was clearly visible) in the underlying .xml for the project, everything looked fine - but my OAuth v2.0 requests just stopped working (can't remember the actual reason for failure).
Similar situation to you - no changes in Dev, no ReadyAPI version change - so I tried re-creating the whole OAuthv2 request from scratch - and that did fix my issue.
Apologies that I can't come up with anything more solid to try and help you fix this.
Cheers,
Rich
