Well, damn. Didnt know that.
Okay, Thanks for your phenomenal help, @pichalite.
Gonna mess around with this proxying and nginx a bit now that everything is moving forward again.
I'm using nodeBB and the password reset is doing some strange stuff.
For example, inputing 2 different password doesn't seem to be a problem :
Also some user click the "Reset" button and don't get any feedback at all.
I'm in production so wondering if an easy fix is possible..
Using postmark to send mail and it's working fine, the problem is with nodeBB reset button and logic.
