lol, it was my antivirus that was blocking your site, but now I get
Not found because of proxy error: Error: getaddrinfo ENOTFOUND extenstions.snap.berkeley.edu
it works fine with https://cors-anywhere.programmeruser.repl.co/forum.snap.berkeley.edu/t/instrument-blocks/5869/9
would it be possible to move the server to a different url? anything with repl.co at the end seems to be untrusted by vpns.
If you can get a domain name for me, then yes.
I can't.
