[SOLVED] Let's encrypt connection refused status 400, validation is pending.

[PhDh]

Hi,
Some months ago I installed proxmox mail gateway and I use let's encrypt in standalone type and challenge type HTTP.
Erverything seemed to work but now the certificate was outdated.
I noticed that because of the SSL warning and it was not renewed automatically.
In the configuration I configured an ACME account and a staging ACME account.
I did not configure a challenge plugins ==> is this necessary? I thought not because it is in standalone.

When I want to renew the certificate now (order certificates now button) I choose SMTP and I get:

Connection refused



Port 80 should be open and when I do a netstat -ln I don't see port 80 but it only opens when the request is made probably?

What am I doing wrong?

Thnx.


UPDATE ==> There was a problem with port 80 and a NAT policy.
Updating that solved it.
