I have never seen an HTTP error number 406 before.

According to https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/406, it means:

[...] the server cannot produce a response matching the list of acceptable values defined in the request's proactive content negotiation headers, and that the server is unwilling to supply a default representation.

It looks like the wiki is referring to local images, which apparently don't exist. When it tries to load them, the server returns a 302 response and forwards to https://github.com/kcat/openal-soft/wiki/, causing it to get an html page which isn't acceptable for an image resource.

I'm not sure if the images got lost somehow, or if they were never there and the references are just placeholders. I guess I'll need to find replacements.
