Hi,
I’ve a post on the url listed which fails to get loaded in Pachli, Tusky and Fedilab. It just gets skipped, not seen at all. It did work originally and notifications came through but at around 150 boosts/favorites something happened. The direct url link works fine, so I’m not sure where to look, to find the problem. Hopefully when I find that out I’ll know better where to report it.
edit: remarkably, I’ve just lost power where the server’s hosted. UPS’s are drained and now unreachable. No idea when the utility co. will get it back up. 
Until then this url won’t work.
edit2: luckily the systems came back up. I thought I may have had to drive over to get them powered up again.
systemctl status akkoma seems to do this when the post gets skipped:-
Jul 13 16:33:08 akkoma mix[489]: 16:33:07.948 [error] Elixir.Pleroma.Web.MastodonAPI.WebsocketHandler received frame: {:ping, “libsoup-keepalive-12”}
Cheers
Gruff.
