"access denied" when loading xfun package from r-wasm.org

[richarddmorey]

I have an app that was working some months ago at https://richarddmorey.github.io/pcurveAppTest/ (source at https://github.com/richarddmorey/pcurveAppTest). It depends on knitr which in turn imports xfun. Now, when I try to load the app, it does not load webr and I get this in the browser console:

GET
https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.js.metadata
[HTTP/2 403  583ms]

Error fetching https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.js.metadata - <?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message></Error>

Indeed, when I try to access https://repo.r-wasm.org/bin/emscripten/contrib/4.4/xfun_0.51.js.metadata via the browser I get:

AccessDeniedAccess Denied

But I see xfun listed under https://repo.r-wasm.org/ - it this an issue on my end, or on the repo's end?
