Server Notices Setup

[sm2x]

Is there any necessary configuration on the side of the Matrix-Synapse server to utilize Server Notices of Synapse-Admin?

[dklimpel]

You have to enable this:
https://matrix-org.github.io/synapse/latest/server_notices.html

[AnonymousWebHacker]

Supposedly in the GUi there should be an option for the server notices?

[dklimpel]

You can send Server notices to users. Therefore is a an admin API.
But you can not configure Server notices. This you have to do in the homeserver.yaml of Synapse.

[sm2x]

assuming this is enabled on homeserver.yaml side already, no further settings on synapse-admin is necessary?

[dklimpel]

There are no stettings in Synapse Admin.

Just enable it on the server side (homeserver.yaml) and using the synapse API, you can use this option, the other variant is using synapse-admin , the web gives you the option to send Server Notices to a specific user.

Bad at the moment, they are only allowed to send msg to a single user, it is not a general msg for the entire server

you can only send msg to a single user??? is this true even if you select multiple users? it is not "Server Notice" if that so

Somehow does not work for me :(


Using Custom Reverse Proxy Apache config since the provided by matrix does not work at all for /healt /_synapse/admin etc
Do you think something is wrong with my conf ->

Is there a reason for the # at the and of line

ProxyPassReverse / http://127.0.0.1:8008/#

Synapse gives you an error 500. I would recommend to have a look at the Synapse homeserver.log file.

There is an example Apache config file: https://matrix-org.github.io/synapse/latest/reverse_proxy.html#apache - but without proxy pass for /_synapse/admin/

@dklimpel Thank you for your answer, i think i did the # to forward also all futrue links to proxy but im not sure anymore.
No i understand why the offiicial Apache config did not work for me, do you have maybe an example config that should fully work with synapse-admin?

The Log i got while sending the notice.

Unfortunately this is also just the generic error message for an "internal server error". You may have to activate more verbose logging or debug settings to get a proper error message.

Thank you for your answer! Where can i set it? in the homeserver.yaml? I dont see any logging parameters beside the logging file path. :/

I think this has to be configured in your reverse proxy. In your case Apache
