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&limit=20&sort=New&type_=Subscribed&auth=
Viewing subscribed communities individually works as does viewing "Local" and "All" communities.
