Probably should be punted over to SOGo support but what the heck.

Just tried to do an apt update and had issues connecting to the SOGo repo:

So(go) for funsies, I tried to see if I could access http://packages.inverse.ca/SOGo/nightly … /InRelease on my local machine, and sure enough, I could.

But when I do a 'curl http://packages.inverse.ca/SOGo/nightly/3/ubuntu/dists/xenial/InRelease' on the iRedMail server, it just sits there.

I poked around on SOGo support (https://sogo.nu/nc/support/faq/article/ … ntu-2.html) and found this:

"In order to access the production builds, you need a proper support contract from Inverse. Continue with the configuration once you received your username and password."

So I'm wondering if maybe I started a 'trial' when I initially installed iRedMail with SOGo?  And now they've blocked my IP from getting updates from their repo?  (/etc/apt/sources.list line:  deb http://packages.inverse.ca/SOGo/nightly/3/ubuntu xenial xenial)

I've successfully updated SOGo via apt before, that's why I'm a bit surprised that I'm not able to do it now.

Actually.. is that IPv6?!  2607:5300:60:37b8::2:1  is this an IPv6 address?  If that's the case, that's really odd!  I know (fairly confident) that the switches my server is in do not support IPv6.

Anyway, I know this isn't explicitly an iRedMail issue, but yall are so great I figured I'd check over here.

Thanks!
