Hello, dear admins. I have same issue as Sean, and I don't think that its
provider problem. Let me explain.

When you trying access to community.kde.org DNS returns 2a02:e980:e::da and
that's wrong:
----------------------
[dut at void ~]$ openssl s_client -connect 2a02:e980:e::da:443
CONNECTED(00000003)
write:errno=104
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 0 bytes and written 320 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
No ALPN negotiated
---
-----------------------------


After some debugging with dns and ssl tools i've found that community.kde.org
must return 2a02:e980:15::da ('e' must be changed to '15'). After that all
works fine.

Same issue with forum.kde.org and so on:

Can you, please, try to check it? Thanks.

Sean, for temporary workaround you can just add forum.kde.org community.kde.org
and so on to /etc/hosts with appropriate ipv6 addresses.
