Posts not resolving after first page

On this mander account, in the standard web client. The front page loads as expected. Clicking next generates the next page URL, but posts do not load in; grey boxes where post information should be and an endless wait. Refreshing and reloading does not fix. Changing from all to local/subscribed feed does not fix. Logging out does fix, but then I'm not logged in.

Edit: Bug persists across devices, phone, pc and boox tablet, and both windows and ubuntu. Suggests server/account-specific issue?

I had a similar (identical) problem for a while on a feddit.org account, but it has since resolved to normal expected behavior without any input on my part.

It's annoying.

Please advise.
