Hi @Jonas_George ,

This looks very familiar to what I ran into a few years ago: Forms not downloading or rendering on reverse-proxied, tunneled ODK Central server

Have you looked into that thread to see if any of the suggestions there work?

Additionally, this page in the documentation may also help.

A couple of questions:

  1. Can you download forms using a mobile device? This will tell you if it is limited to Enketo or generally an issue with the XLSForms.
  2. Have you tried looking at the docker compose logs to see where the error originates from?

Best of luck!

Thanks @jniles.

I have had it working. I was missing some of the Upstream settings from the documentation. After reviewing your post I had to go through the installation guide again and I didn't have to do much for it to start working again.

Another necessary thing I did was to delete the whole installation (central folder) and start the new installation which brough the latest version as well.

Thanks again. Now all is working as expected.
