Ssl and ipv6

Hello,

I cannot access aur and it seems that it's a SSL issue with IPv6.

curl -v https://aur.archlinux.org/                                                                                                                                                                           
*   Trying 2a01:4f8:160:3033::2...
* Connected to aur.archlinux.org (2a01:4f8:160:3033::2) port 443 (#0)
* ALPN, offering http/1.1
* Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH
* successfully set certificate verify locations:
*   CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: none
* TLSv1.2 (OUT), TLS header, Certificate Status (22):
* TLSv1.2 (OUT), TLS handshake, Client hello (1):
STAY STUCK HERE

But forcing ipv4 (curl -4 -v https://aur.archlinux.org/ ) work fine
And ipv6 ping work fine too (ping 2a01:4f8:160:3033::2)

Any idea ?

Thanks !

Re: Ssl and ipv6

Below is partial output of that command on my system.
It does look like the "Server hello" reply doesn't reach your system.

Maybe it's blocked by a firewall or proxy ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Ssl and ipv6

That's a good point.
My router is not supposed to do any fancy things but people have already express some issue like this.

Thanks for the help

Re: Ssl and ipv6

I'm having a similar issue. I have very spotty connections when making RPC calls to the AUR. Accessing any no other *.archlinux.org page is fine.

A user of mine in Europe was having no such trouble, and he reported his browser always dealt in ipv4. My browser (and computer in general) seem to use ipv6 to access the AUR.

Any ideas?

EDIT: Interesting, it took me several minutes and many retries to get this to post. I thinking it's a similar issue. Also see: https://bbs.archlinux.org/viewtopic.php?id=206820
