I was getting 502 Bad Gateway. When I pinged Lemmy.ml I got an IPV6 address. It disabled IPV6 on my local computer and now when I ping I get a IPV4 IP address it works now.
I am wondering if DNS is screwed up on the IPV6 network for Lemmy.ml.
Note. This could totally be something on my end, I really haven't done much with IPV6 but it did solve the 502 Error so I might do the same for you.
Edit. I had a few people say turning off IPV6 on their end fixes the 502 Bad Gateway, so it looks like it has something to do with IPV6.
You are right, I forgot to configure IPv6. Will be fixed shortly.
Edit: Should be fixed now.
Thanks for mentioning the IPv6, I've been banging my head all day trying to figure out why I kept getting the 502 yet no one was complaining anywhere and isitdown was showing the server as Up.
I forces my DNS to resolve only IPv4 for lemmy.ml and now I can use it.
My suspicion is that nginx is misconfigured and not listening via IPv6. Or maybe the AAAA record is pointing to the wrong IPv6 address.
@nutomic@lemmy.ml Thanks for upgrading the server!
