You didn't specify which OS you are using. I was having the same problem in Ubuntu (under WSL), and after checking that the anaconda websites were whitelisted in my work network, I solved it by upgrading openssl from 1.1.0g to 1.1.1b.
(geo) user@host:~$sudo apt-get upgrade openssl
(...)
(geo) user@host:~$ openssl version
OpenSSL 1.1.1b 26 Feb 2019
