Sysupgrade Server Unresponsive?

Hello - Is anyone having issues connecting to sysupgrade.openwrt.org? Over the past few days I had to run auc multiple times to complete an update and now it is stopping with a No Data Available (61) error.

I recently installed luci-app-unbound so wondering if it's me or if others are having issues, too?

Thanks!

It's working as of this time.

I have the same cryptic error message from auc. What exactly the tool tries to tell me?
