REST API status 429 on certain requests

[glowcloud]

Hello all,

I currently have an issue with the Jira API (v2) when I try to modify versions.

I can add and modify for example comments and create new versions. However, when I try to delete comments or modify versions, I get the error 429. I am aware of the discussions around rate-limiting here: https://community.developer.atlassian.com/t/rate-limiting-guide-for-jira-and-confluence/43360, however I don’t see how this could be a rate issue since I execute the script manually with hours and even days between requests, and much larger GET requests still run through without any issue. I also get no retry-after indicating how long I should wait, nor do I get the X-RateLimit-Remaining field (however it appears in successful GET requests, showing me that I should have requests remaining).  To me this at first looks a bit like an authorization issue since the error occurs only on certain actions (PUTS work on comments but not on versions) however when logging in, I can perform all the desired actions manually.

I send my requests through KNIME which already implements a retry after functionality, however when using this, the server returns a 404 the second time.

As I am relatively new to Jira and the REST API in general, I would be happy about any tips or ideas what I am doing wrong.

Update: I found out that this is most likely due to the internal server and security policy
