Previously you said you are not using Apache for your web server, what are you using ( rt standalone nginx etc )?

Can you do a simple curl request against the RT REST2 API and share the request and the error returned?

Thanks Knation, finally fixed with apache server by sing the method that you suggested me in the other question.
