Not seeing banner image in my lemmee community

EDIT: I should have posted this in the Support community - as others are also doing.

Just noticed tonight that when I visit my FullMoviesOnYouTube community, the banner image is not shown.

I tried linking directly to it:

https://lemm.ee/pictrs/image/642b333b-5c37-4d39-af9f-cc876de484fc.webp?format=webp

And got this error:

{"error":"unknown","message":"Request error: error sending request for url (http://10.0.0.3:8080/image/process.webp?src=642b333b-5c37-4d39-af9f-cc876de484fc.webp): operation timed out"}

Any idea what's up? It's definitely been working as of just last week.
