Multiple Lemmy apps serve the first ‘page’ of posts fine - even new posts or updates - but upon scrolling and requesting the next page, Boost gives an error message “timeout”, and Blorp just doesn’t load anything else (per app implementation, I know).
I have this issue too. Except for me the issue is only happening to me in Jerboa, but opening the site in a mobile browser allows me to go past the first page.
Are you logged in when you are viewing in the browser?
I just realized I normally use the oldsh.itjust.works to access this site and that works fine for me both logged in/out, but after trying the normal sh.itjust.works site I see the page 2 loading issue on desktop too now.
