juliaup: MacOS: Download timeout but url works manually

The url works when I try via a browser, but times out via juliaup

I pushed a new build to the release preview channel that uses a different rust package for the downloads. Would be great if folks can give that a try if you are on Linux or Mac. You can switch your installation over to the release preview channel by running juliaup self channel releasepreview.

I have this problem, and have tracked it down to my own misconfigured setup where I have an IPv6 address, but no IPv6 route to the Internet. Possibly others have had the same problem as me.

The problem is as follows:

I have an ISP who does not offer IPv6 (name and shame: Telia Finland)
My router’s DHCP settings is set to give out ipv6 addresses
- Disabling this fixes the problem
The problem started when I switched my DNS to Google DNS from my ISP’s due to reliability issues
- It looks like my ISP may have previously filtered AAAA records to avoid people trying to use IPv6

As to why the problem occurs for juliaup and not in the browser, it seems some software, including web browsers and curl will retry with the A record when they can’t connect to the AAAA record (perhaps web browsers figure out in advance that IPv6 is not usable beyond the router), whereas wget and ureq will not.

I just checked, and hyper, the underlying package that reqwest uses, does implement the happy eyeball approach. So, presumably it should all work now. I am going to close this issue for now, if you run into any similar problems with the latest version again, please either reopen here or a new issue.

Oh wow, that is amazing detective work!

I think this probably has to be addressed upstream in https://github.com/algesten/ureq, right? That is what we use for downloading on Mac/Linux. On Windows we use Windows APIs for downloading, and my assumption would be that those deal with this kind of stuff automatically.

… and one day later still not working. So it’s perhaps reasonable to reopen this issue.
