I'm on Ubuntu linux, using Ruby 2.4.2p198 and http 3.0.0

When I try to make a connection to a Dahua camera, I get this:

> HttpClient.basic_auth(user: 'admin', pass: 'admin').get('http://192.168.1.108/cgi-bin/configManager.cgi?action=getConfig&name=General')
=> #<HTTP::Response/1.1 401 Unauthorized {"Www-Authenticate"=>"Digest realm=\"Login to 2L05ABCPAA00246\",qop=\"auth\",nonce=\"671353293\",opaque=\"f1f47336b1c3f6c079c49377096a6ed59f81806c\"", "Connection"=>"close", "Content-Length"=>"0"}>
>
> HttpClient.basic_auth(user: 'admin', pass: 'admin').get('http://admin:ad...@192.168.1.108/cgi-bin/configManager.cgi?action=getConfig&name=General')
=> #<HTTP::Response/1.1 401 Unauthorized {"Www-Authenticate"=>"Digest realm=\"Login to 2L05ABCPAA00246\",qop=\"auth\",nonce=\"2128627133\",opaque=\"f1f47336b1c3f6c079c49377096a6ed59f81806c\"", "Connection"=>"close", "Content-Length"=>"0"}>

However, wget works:

$ wget 'http://admin:ad...@192.168.1.108/cgi-bin/configManager.cgi?action=getConfig&name=General'
