Thread:Project:Support desk/IPv6 HTTP on 2620:0:861:ed1a::1 (https works)

I wonder where to ask this question. I am just a user of en./nl.wikipedia.org.

My ISP turned on IPv6 on my modem several days ago, and now I have issues connecting to http://en.wikipedia.org and http://nl.wikipedia.org on HTTP. When connecting HTTPS it works fine. DNS lookup currently points me to [2620:0:862:ed1a::1] for most wikimediafoundation related websites. Connecting to http://[2620:0:862:ed1a::1]/ in the browserbar, gives a response: "This domain points to a Wikimedia Foundation server, but is not configured on this server. That’s all we know."

Can you help me? Google directs me to the HTTP version of the sites most of the time.
