Sorry for the possible question misplacing but I don’t now where can I ask about it.
I’ve got a weird situation with elixir-lang.org access. I always get ERR_CONNECTION_RESET when I try to open elixir-lang.org from my home network. Any device, any OS, any browser within the network produce the same situation. If I connect from any other place with the same devices - everything is ok. All other resources (sites) work well. I’ve faced this situation for the first time a few months ago and since then can’t get any info from elixir-lang.org.
Please point me to the place where I can resolve the situation.
No IPv6 address detected
You appear to be able to browse the IPv4 Internet only. You will not be able to reach IPv6-only sites.
This means your IPv6 support is off. Otherwise it may be on, or partially on which may be worst.
I had the problem with reaching to some sites because they were slightly misconfigured (this forum site as well), and I had to disable IPV6 altogether on my Internet connection (Orange Poland).
I don’t have IPv6 connection enabled to check this is the issue now, but I do think it may be (although the ipv6 validators say the site works under IPv6 - I would not trust this is completely good test).
Seems that IPv6 might be the problem. I’m getting much worse ping results (29ms with IPv4 and around 200ms with IPv6, as well as packets lost on IPv6) and it’s Teredo. Pretty weird thing is that elixir-lang.org is the only site I’m getting troubles with.
It is because of Cloudflare. Cloudflare always has issues with certain providers (or certain countries) and certain setups. Others like Fastly have similar issues. Only way for Elixir to really fix it is to move it to another server that does direct hosting (I have one if needed, that is what my mirror runs on).
Of course not, they are distributed randomly to help equalize load.
The main thing is that Cloudflare needs to be Gone from anything related to Elixir (and likewise things like Fastly need to never be added either). This is a major issue with such services (in other language areas as well like Ruby and Maven’s systems).
After some time spent on investigation (both mine and provider support guys) and testing it became clear that IPv4 (!!!) connection doesn’t work from my ISP network. The endpoint refuses IPv4-connection. Now I have correctly configured IPv6 settings and routing and everything works as it should - but with IPv6 connection only. Since IPv4-connection reset happens from the other side it looks like the problem in the cloudflare or elixir-lang.org configuration (at least it is the first thought).
My ISP support would like to discuss this situation with somebody from elixir-lang.org support: they are care much of their services quality and would like to solve the issue together. So if you know any contacts (e-mail, probably) I can send to them please let me know.
The problem is that there are not many reliable, free or cheap alternatives that support the features we need. And while it’s nice that you offer to provide your servers we can’t use servers that we don’t have control over and can’t administer if something goes wrong.
Since elixir-lang.org is hosted by Cloudflare the best thing would be if you contacted Cloudflare directly, otherwise we would just be forwarding the messages.
