Hello,

I'm attempting to use this gem and get the following errors when attempting to make a connection:

/Users/user/.rvm/gems/ruby-2.7.2/gems/clever-ruby-2.0.2/lib/clever-ruby/api_client.rb:292: warning: URI.escape is obsolete
/Users/user/.rvm/gems/ruby-2.7.2/gems/ethon-0.12.0/lib/ethon/easy/operations.rb:29: [BUG] Segmentation fault at 0x000000016ef22a00
ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [arm64-darwin20]```

And then I get a huge crash report.

I'm getting a similar error:

Does someone know what it is about?
