I continue to get the following error when trying to curl an https:// endpoint:

curl: (1) Protocol "“https" not supported or disabled in libcurl

I've tried manually installing with --with-darwinssl:

wget https://curl.haxx.se/download/curl-7.58.0.zip
unzip curl-7.58.0.zip
cd curl-7.58.0
./configure --with-darwinssl
make
sudo make install

I think this is installing to /usr/bin/curl but I've tried this one as well as what's in /usr/local/bin/curl and continue to get the same result. From the -V details, it seems like SSL should be enabled:

/usr/bin/curl -V
curl 7.54.0 (x86_64-apple-darwin17.0) libcurl/7.54.0 LibreSSL/2.0.20 zlib/1.2.11 nghttp2/1.24.0
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp
Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz HTTP2 UnixSockets HTTPS-proxy

I've also tried:

brew uninstall --force curl
brew cleanup --force -s curl
brew prune
brew install curl --with-openssl

But no luck. I'm about out of ideas here, any help is appreciated

Protocol "“https" not supported
          ^

See that extra quotation mark? That's a curly quote, not a normal double quote. curl thinks the protocol is literally called “https.

I bet you copy/pasted a URL from a web page which included that symbol and curl is trying to interpret it as part of the protocol. Remove it, and curl should start working as expected.

    Nice catch, https should work "out of the box" – Mateusz Szlosek May 9 '18 at 17:07
