Was the module renamed? Do I have to file an issue on the nixpkgs repo? Is there some place, where all the renamings are documented? I’m a bit lost here…
The matrix-sliding-sync package has been removed, since matrix-synapse incorporated its functionality. Remove services.sliding-sync from your NixOS Configuration, and the .well-known record for org.matrix.msc3575.proxy from your webserver
Thanks for the quick reply, exactly what I was looking for! Can sliding-sync be somehow enabled when using synapse alternatives (such as conduit or conduwuit)?
I was about to suggest a sliding sync proxy but: “The proxy works fine with Dendrite and Synapse, but it doesn’t work well with Conduit due to spec violations in the state of a room in /sync.”
