[Bug 1864689] Re: openssl in 20.04 can't connect to site that was fine in 19.10 and is fine in Chrome and Firefox

[Jonathan Kamens]

I may be misunderstanding something, but as far as I can tell this is
not a cipher mismatch problem.

According to
https://www.ssllabs.com/ssltest/analyze.html?d=www.toodledo.com, the
site supports TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256. According to
"openssl ciphers", openssl supports ECDHE-RSA-AES128-GCM-SHA256, which
apperas to be the same thing. But `curl -v --ciphers ECDHE-RSA-AES128
-GCM-SHA256 --tlsv1.2 --tls-max 1.2 https://www.toodledo.com/` still
fails.

Title:
  openssl in 20.04 can't connect to site that was fine in 19.10 and is
  fine in Chrome and Firefox

Status in openssl package in Ubuntu:
  New

Bug description:
  openssl in Ubuntu 20.04 (focal) refuses to connect to a web site that
  openssl in Ubuntu 19.10 (eoan), Chrome, and Firefox are all happy to
  connect to.

  Reproduce with: `curl -v https://www.toodledo.com/'

  or: `openssl s_client -connect www.toodledo.com:443`

  or: `python3 -c 'import requests;
  requests.get("https://www.toodledo.com/")'`

  or: `wget https://www.toodledo.com/`

  These worked in Ubuntu 19.10 and don't work in 20.04.

  I've tried all sorts of things to debug this further and I've just run
  into walls. I hope someone who understands more about this stuff will
  be able to figure it out.
