Failing versions of early Greenlock v2.x (maybe 3.x?)

[coolaj86]

The domain I used for security telemetry (ACME client User-Agent and contact email) in one of the original versions of Greenlocks has lapsed (after several years of going unused).

If you're version of Greenlock is affected, updating to the lastest minor release should fix it:

• 2.0.1 => 2.x
• 3.0.1 => 3.x

The change should have never caused failure, it was simply a bug in the async / promise handling. The patch that was released several years ago fixes it.

I just found out it expired a few weeks ago, so if this still were a problem I imagine I've have heard about it by now. If it turns out to be a big issue for someone over the next 2.5 weeks, it's still reclaimable.

After that I imagine it will be snagged up by domain snipers who want thousands of dollars for it (since it has had residual traffic all this time), which I don't care to pay.
