When users visit the site only some of the images on the page show. Checking Chrome dev tools shows that the missing images are failing with "server unavailable" errors. The image is there if you go to it directly.
This appears to be random. Images show sometimes but not others. I have erased the cache, rebuilt the search index and the asset list. No change.
The client says that the site sometime fails completely but I have yet to witness this.
I have VPNed from various locations and it seems to be the same no matter where I'm coming from.
The hosting company says the only error they see is "image missing" and the DB connection is fine.
Any help would be great.
