I've had success unregistering the service worker, and clearing the cache. I have the feeling that sometimes a negative/bad response is cached and then it never loads even when the service would otherwise respond.

(ive mostly had this on non-blahaj communities but that at least was the fix for me)

I couldn’t open the site on iOS earlier today, I’m just getting a blank screen

Update: pretty sure it is actually the VPN being blocked by blahaj.

I think before it was just cached or something when I tried to reload. I saw a pretty clear example of an image not working then I turned the VPN off and it loaded.
