Description
While 2026.2.0 runs without problems, starting the proposed standard setup (https://github.com/cryptpad/cryptpad/blob/main/docker-compose.yml) causes an error:
["ERROR","2026-04-02T19:38:28.064Z","INVALID_CUSTOM_QUOTA_API",{"error":"INVALID_PROTOCOL","value":"localhost:3002"}]
When trying to reach the web frontend, you get a timeout (directly) or Bad Request (nginx reverse proxy; logs show upstream timeout)
Additional information: I use a podman-compose setup, but I would guess it should occur the same way in a docker-compose setup. Please let me know, if I am wrong here.
Steps to reproduce
- Follow the docker instructions on https://docs.cryptpad.org/en/admin_guide/installation.html
- Don't build your own image, but use latest (or version-2026.2.2) tag.
- Start with docker-compose/podman-compose up
