Jira rest api issue export with cookie authentication returns 401

[Deleted user]

Dear community,

im actually writing an exporter for all project issues in java using cookie authentication.

In the end, i want to safe all json data to a file i did get.

Problem: I do constantly receive http 401 as i use my session id (received from basic auth. before) as my cookie variable.

I did make sure that the syntax of my cookie is correct, so there have to be another detail i have missed. So my jsonData at the end of code still remains empty. Is another authentication needed?

I have full access to the project and everything else works fine.
