I can recreate this, the error I'm seeing on the server side is Page limit is > 10. I wish client side gave a better error message here than counldnt_get_posts.

This seems to have been a deliberately changed in this PR to fix comment list sorting DDOS exploit. How this affects clients depends on if they use page or page_cursor, which has no limit.

For now I'll just patch our Lemmy to increase to increase the limit to something more reasonable, like 100. Probably need to upstream this as well as it'll affect every instance on 0.19.14.

Likely is. I'm experiencing something similar with timeouts instead, but it happens across clients (and less often since a server upgrade). So probably a change in configuration for your instance, or an uptick in usage/growing userbase?

Either way I'd check to see if this happens on other clients too, first.
