Pkg: unable to connect to sa.pkg.julialang.org

Cheers,

I’m having this issue under Julia 1.8.2. A clean Julia install has not been able to solve it.

Are you able to download https://pkg.julialang.org/registries in the browser or using curl on the command line, e.g. with curl -L https://pkg.julialang.org/registries.

No, I can’t. By the way, issue is being observed since last Sunday on three different computers, each one under very distinct network installation.

(base) ciro@pc-ciro:~$ curl -L https://pkg.julialang.org/registries
curl: (7) Failed to connect to sa.pkg.julialang.org port 443: Connection refused
(base) ciro@pc-ciro:~$

Confirmed that sa.pkg.julialang.org is not allowing connections. I’ve moved this to a new topic since it’s an unrelated issue. That server may be having issues.

Server is back. Thanks.

Yep, I pinged @staticfloat and he fixed it. Full disk. Thanks for the report!

Just to let know sa.pkg.julialang.org seems to be dead again. @staticfloat

Looks like DNS issue. Output from dig

I’m having the same issue right now. Seems to be only with sa.pkg.julialang.org; other domains, like us-west.pkg.julialang.org, are working fine.

Hmmm, I’m not having the issue. When you have this issue, can you please show the output of the following:

$ dig @1.1.1.1 sa.pkg.julialang.org
$ curl -vL https://sa.pkg.julialang.org/meta

@staticfloat, sorry for the long delay. I just saw your reply today, as I came back because I’m having the same issue again.

user@hostname ~ [60]> dig @1.1.1.1 sa.pkg.julialang.org

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

For some reason curl is not resolving the domain to the same server? My system/router resolver seems to be pointing to the correct address:

user@hostname ~> nslookup sa.pkg.julialang.org
Server:		192.168.15.1
Address:	192.168.15.1#53

Non-authoritative answer:
sa.pkg.julialang.org	canonical name = pkgserver-sa.ip.cflo.at.
Name:	pkgserver-sa.ip.cflo.at
Address: 15.228.68.108
12

Are you certain you haven’t done something like overridden the resolver in /etc/hosts or similar?

Oh, yeah! This is the old address I’ve set in /etc/hosts previously when the domain was failing to resolve. Removing the line fixed the issue.

Sorry for disturbing you.
