Can't connect to secure yahoo mail over IPv6
« on: November 22, 2020, 05:00:39 PM »

For the past few weeks, I've been having trouble connecting to yahoo mail.   Does anyone know what could be the problem?

I try this with HE IPv6 tunnel.  Nothing happens except a timeout after five minutes.

Code: [Select]
$ curl --verbose --verbose https://mail.yahoo.com
* Rebuilt URL to: https://mail.yahoo.com/
*   Trying 2001:4998:1c:800::1000...
* TCP_NODELAY set
* Connected to mail.yahoo.com (2001:4998:1c:800::1000) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* successfully set certificate verify locations:
*   CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: /etc/ssl/certs
* TLSv1.3 (OUT), TLS handshake, Client hello (1):
* Operation timed out after 300156 milliseconds with 0 out of 0 bytes received
* stopped the pause stream!
* Closing connection 0
curl: (28) Operation timed out after 300156 milliseconds with 0 out of 0 bytes received

whereas if I do:
Code: [Select]
$ curl --verbose --verbose -4 https://mail.yahoo.comthe response is instantaneous.

A plain http://mail.yahoo.com over IPv6 (port 80) forwards immediately to https://mail.yahoo.com (port 443) which times out.  So http to yahoo over IPv6 is good.

I can get to other IPv6 sites just fine, he.net, youtube, google... with and without https.  ipv6foo on my browser verifies IPv6 connection usage.  I'm filling out this form with https://forums.he.net (port 443) and the site is quite responsive.

I've reproduced this problem on Windows, RHEL and Ubuntu.
