If you're experiencing slow curl connection, or slow python requests connection.

For me, the real issue is because the dns_resolution is very slow.

If you make a debug on curl request, with command:

$ curl -w "dns_resolution: %{time_namelookup}, tcp_established: %{time_connect}, ssl_handshake_done: %{time_appconnect}, TTFB: %{time_starttransfer}\n" -o /dev/null -s "https://www.google.com"

For me, the dns_resolution showing 8.012.

Then, I've found the solution to this problem is to add those value in /etc/resolvconf/resolv.conf.d/head
After that, my dns_resolution showing 0.012. dang!
