Hi everyone, I’m having an issue with the Line Listing app in DHIS2 2.41 and wondered if anyone has come across this before. When I select: Input: Enrollment Select any tracker programme Click Program dimensions I receive the error: Couldn’t load dimensions: Forbidden ![image](https://dhis2.b-cdn.net/uploads/default/original/3X/7/0/70a37d8560338a75f5639d85e3fe17b96081d238.png) A few things I’ve checked: It seems to be happening for all tracker programmes. It also happens for programmes that I built myself. Event input works without any issues - the error only occurs when using Enrollment input. I am logged in as a superuser, so it doesn’t appear to be a user authority issue. The programmes open and work correctly in Capture. Has anyone seen this before, or have any suggestions for what might be causing it? Many thanks! Jessica ---

Hi @jschofieldwood I have two requests please: 1. Please update the Line Listing app to the latest version by going to the App Management app then when testing again, use the [browser’s Guest mode](https://support.google.com/chrome/answer/6130773). 2. Debug and share error from the Network log (F12, DevTools → Network Tab): a) Select enrollment b) Select the tracker program c) Open the Network tab - Click F12 to open the DevTools then select Network tab d) Select ‘program dimensions’ while monitoring the network tab - check the request for the dimensions and get the error from the response: Thanks! ---

Hi, Thanks for your response and suggestions. I checked App Management, but the Line Listing app is not listed there, so I wasn’t able to update it separately. Our instance is running **DHIS2 2.41.8.2**. I then tested in a Chrome Incognito window and reproduced the issue. Here is the Screenshot of the Network log showing the failed request (403) and the Screenshot of the Response from the failed request ![image](https://dhis2.b-cdn.net/uploads/default/original/3X/8/1/817c237f7e944b5e032462f88bd880fed5c990bd.jpeg) ![image](https://dhis2.b-cdn.net/uploads/default/original/3X/e/9/e92103f2952293c2ec595d0741a812e30c9f0d22.png) Please let me know if you need any further information.

Yes, this is a generic issue. It’s not clear why you’re facing this issue on the server side. Let’s please grab the Catalina.out log (without the authentication/sensitive info) then share it here please. Thank you! ---

I don’t think I have access to that, as BAO hosts our instance of DHIS2. I can ask them for the logs if that’s the next step? ---

Troubleshooted your images (very helpful!) with Claude which said that it is something that needs to be solved with BAO, not an DHIS2 issue: In the **Response** tab of the failing `dimensions` request, the body is: ```auto 403 Forbidden — nginx/1.30.3 ``` That’s an **nginx** error page, not a DHIS2 error. It means the request is being blocked by the reverse proxy / web application firewall sitting in front of DHIS2, **before it reaches the DHIS2 application server**. This is a hosting/infrastructure configuration issue on the instance, so the next step is with BAO - ask them to check the **nginx access/error logs and any WAF (e.g. ModSecurity) logs** for the request: `GET /api/analytics/enrollments/query/dimensions?...` That will show exactly which proxy/firewall rule is returning the 403 so they can whitelist it. The Event input works because its (near-identical) request isn’t being caught by the same rule. Hope that helps! Karoline DHIS2 Product Manager ---
