Hello @thomaspoignant so I just made some changes.

[thomaspoignant]

Hey @CollinsC1O thanks for your update but it seems that your commit 92818f3 has removed all recent new features that we have introduce recently.

Can you try to check what happened?
My guess is that the resynchronisation of your repo did not work properly.

I also so that you did not addressed the comments about the README.md file #2611 (comment) and about the change in the relay proxy configuration #2611 (comment) and #2611 (comment).

[thomaspoignant]

There are still some issues, you have removed some existing feature in this PR.

[CollinsC1O]

Hello @thomaspoignant. Corrections have been implemented, waiting for your review
