Hey, I am trying to use Taiga Selfhosted (CE) Kanban feature. I get errors when I try to view, edit or delete cards in custom columns/tasks. The issue I get is the following: ```auto GET https://me.tld/api/v1/userstories/by_ref?project=1&status__is_archived=false 400 Bad Request ref param is needed ``` I also get a second error: ```auto GET https://me.tld/api/v1/userstories/by_ref?project=1&ref=2&status__is_archived=false 400 Internal Redirect ``` I suspect it might be related to a dual proxy situation (since I’m running Taiga with its default gateway behind nginx proxy). Thank you for any explaination 🙂 Edit: running on taigaio/any:latest with default configuration apart from secrets and stuff. ---

Hi @Daerendor I’m not sure what it happening in your environment: - the first request is made using directly the API? or you have a way to reproduce the error using the UI? - the second error, is made using the API? or you did change something to make the request have the `ref` param? - do you have some docker logs that may help to understand the error? The dual proxy situation is expected; it’s not the only way to serve Taiga and you may want your own configurations, but you should know about nginx, exposing ports in docker, etc. Cheers! ---

Hi! I had the same problem and I found the culprit. It was the addon ClearURLs that deleted the ref parameter. After disabling the addon (it doesn’t have whitelist ): ) I was able to use Taiga normally. If anyone face the same problem and has the addon, disable it! ---

This should imho be part of the docs. I just found that I had the same problem, Taiga itself was all working fine.
