Hello,

you have a network issue when lego tries to do DNS calls.

It can be related to a firewall, a local DNS, etc.

[gmeghnag]

You are right, the same command succeeded from a cloud instance (I don't know what's wrong with my env since it is open).
Sorry for bothering you.

P.S.: lego is a wonderful tool, congratulations.

Hello,

I'm having the same issue, how can I test why it times out ?

Using dig @1.1.1.1 [mydomain] I was able to see that my domain name points to the right IP address, and this was done on the server so it should be able to make DNS calls correctly.

I can also see TXT records with name _acme-challenge.[mydomain] being created on my cloudflare dashboard.

Thanks
