UnifiedPush not working with Conversations

[blaueente]

Steps to reproduce

1. Select "Conversations" as UnifiedPush provider
2. Run notifications Troubleshoot tests

Outcome

What did you expect?

Working notifications (they work with other demo programs)

What happened instead?

Error
"Fail to check the gateway
https://up.conversations.im/_matrix/push/v1/notify: HTTP 404 Not Found"

Apparently the URL for using conversations as a push gateway is wrong. Maybe it's the "_matrix"? or is "v1" a too old version? Anyway, testing with https://f-droid.org/packages/org.unifiedpush.example/ works.

Are you willing to provide a PR?

This is because ntfy includes a matrix gateway (https://github.com/binwiederhier/ntfy/blob/630f2957deb670dcacfe0a338091d7561f176b9c/server/server_matrix.go#L16) that is, it receives calls to /_matrix/push/v1/notify and sends them out via UnifiedPush.

conversations (https://codeberg.org/iNPUTmice/up) does not contain a matrix push gateway, and that is needed for EXA. So it won't work. Either conversations' up needs to include a Matrix gateway, or the Matrix homeserver needs to be taught to directly speak to a UnifiedPush server.

The Matrix gateway is what is called the "push gateway" in the diagram at https://spec.matrix.org/latest/push-gateway-api/#overview

What is EXA? I see the same issue with NextPush, which works fine as a UnifiedPush provider with normal Element on android, so I'm confused why NextPush would need matrix-specific changes for ElementX to work?

Looking at the code, it should fall back to use the standard matrix.org gateway if the UnifiedPush server does not provide one. Not sure what is happening there, I am not a developer myself.
P.S. EXA is short for Element-x-android

At some point this was working with EXA and NextPush but seem to have stopped.

I'm having this problem too. It started after I updated Element X to the most recent version.

#3185 seems to request what you describe.

[p1gp1g]

The cause of this issue is that EAX now expect a self-hosted matrix push gateway and never fallback to a default one: #3388 Reverting this should fix this issue

I have a similar issue with the gCompat UP-Distributor (https://unifiedpush.org/users/distributors/fcm/): When I run Settings > Notifications > Troubleshoot, I get "https://fcm.distributor.unifiedpush.org/_matrix/push/v1/notify is not a Matrix gateway".
