    Debian Buster and ISPConfig 3.1.15p3
    certbot 0.31.0
    I've read all suggestion about LE on Debian 10 and ISPC3, but stucked, please help.
    I've installed Ispconfig 3 on Debian 10 and Apache from perfect setup. I've managed to issue cert for main ispc panel from LE. But now when I want to test LE on new site I cant get new cert. I have such error in letsencrypt.log:
    "detail": "Fetching Timeout during connect (likely firewall problem)",
    "url": "",
    "hostname": "",
    "value": ""
    "detail": "Fetching Timeout during connect (likely firewall problem)",
    "url": "",
    "hostname": "",
    Detail: Fetching Timeout during connect (likely firewall problem)
    Detail: Fetching Timeout during connect (likely firewall problem)
    certbot.errors.FailedChallenges: Failed authorization procedure. (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching Timeout during connect (likely firewall problem), (http-01):

    I've putted hello.txt to this site and its works locally and remotely. What could be the reason for this error? Tried all tips what I found on this forum. Please advice what I am missing.

    how did you get the isp panels letsencrypt cert?

    how did you test this? was the remote test from a machine on the same network or from a machine outside the firewall and not using a vpn?

    either apache isn't running, in which case all of your tests would have failed
    it does look like there's a firewall in the way blocking at least port 80..

    or maybe you do have port 80 open on your firewalls but only allowing connections from a few specific ip's?

    Soooory, I'm totally noob. You are right, this ip was blocked on edge router only for local traffic. Fixed, and LE works. Thx a lot.
