Background information

• Dendrite version or git SHA: 0.13.0+
• SQLite3 or Postgres?: Postgres
• Running in Docker?: yes
• Client used (if applicable): Element Android App

Description

• What is the problem: since Dendrite-monolith 0.13.0 a login with Element Android is not possible
• Who is affected: as far as I can tell, everyone using dendrite 0.13.0 onwards and Element Android
• How is this bug manifesting: "unrecognized request" message below the custom server URL input field.
• When did this first appear: Dendrite-monolith 0.13.0

Steps to reproduce

• install / upgrade to dendrite-monolith inside docker 0.13.0 or later
• input matrix domain of dendrite-monolith in Element Android App
• error "unrecognized request" will be shown below the input

There is nothing in the container logs regarding the client error.

Which version did you upgrade from?

I upgraded from 0.12.0 but was also able to reproduce with a clean 0.13.0 install.

I had the same issue. Properly setting up a .well-known/matrix/client fixed the issue.

Same issue here. I can confirm that setting up a proper .well-known/matrix/client response solves the issue.

I had to deploy nginx with a static response just for this:

https://github.com/mkroman/k8s/blob/d857aee6c3d4a5d600b9f788a32e2ddc8ae3633d/kustomize/dendrite/base/configmap.nginx-config.yaml#L9-L31

It would be great if Dendrite could provide this endpoint just like it provides the .well-known/matrix/server endpoint.

According to the specs at https://spec.matrix.org/v1.3/client-server-api/#well-known-uri a 404 should immediately trigger a IGNORE and the client should revert to using default values, which in my case would be the base domain.. But for some reason, the android client doesn't do that.
