Logged in and subscribed to a dozen communities. Clicking on "Subscribed" results in a spinning circle that goes away after ~30 seconds, but the posts never display.
Firefox developer tools provides message: "504 Gateway" or "Timeout occurred while waiting for a slot to become available" for url https://lemmy.linuxuserspace.show/api/v3/post/list?page=1&%3Blimit=20&%3Bsort=New&%3Btype_=Subscribed&%3Bauth=
Viewing subscribed communities individually works as does viewing "Local" and "All" communities.
For me my instance doesnt federate with lemmy.linuxuserspace.show
My fix is to post a link somewhere and click on it, this is the only way to force open the community.
It loads a while and suddenly it works, my theory is this triggers manual federation and now they work together
