TImeout during connect

[adilei]

Hi All, I’m getting a timeout error altough it seems my nginx repsonds to outside requests

My domain is:

leibowitz.ddns.net

I ran this command:

sudo acme-nginx -d leibowitz.ddns.net --debug

It produced this output:

2020-04-30 10:14:04,929 - ERROR - leibowitz.ddns.net challenge did not pass: {u’status’: u’invalid’, u’cu’invalid’, u’validationRecord’: [{u’url’: u’http://leibowitz.ddns.net/.well-known/acme-challenge/TXXLAnKliBnjN9eAys’, u’hostname’: u’leibowitz.ddns.net’, u’addressUsed’: u’109.186.69.244’, u’port’: u’80’, u’9.186.69.244’]}], u’url’: u’https://acme-v02.api.letsencrypt.org/acme/chall-v3/4269570543/iMuwrQ’, u’tokg2YP-G4SdmUv5KliBnjN9eAys’, u’error’: {u’status’: 400, u’type’: u’urn:ietf:params:acme:error:connection’ttp://leibowitz.ddns.net/.well-known/acme-challenge/TXXLAndy_zy2a2O_1pg2YP-G4SdmUv5KliBnjN9eAys: Timeoutirewall problem)’}, u’type’: u’http-01’}], u’identifier’: {u’type’: u’dns’, u’value’: u’leibowitz.ddns.n05-07T07:13:09Z’}

The operating system my web server runs on is (include version):

Ubuntu 14.04

My hosting provider, if applicable, is:

Hi @adilei

if you want to create a certificate via http validation, a working port 80 is required.

Your port 80 doesn't answer. Check your firewall and router setup.

Thanks @JuergenAuer. However port 80 actually does respond for me

It doesn't answer. See your online check, ~~3 hours old - https://check-your-website.server-daten.de/?q=leibowitz.ddns.net

Timeouts checking http.

You use your internal connection.

I can see it is failing the check, however I am getting a response even from my smartphone on the mobile network, so router/firewall seems fine. Any chance this is ISP related?

@adilei

If it's your WiFi, that's the same.

Online checks (like "check your website" or Letsencrypt) must be able to see your port 80 answer.

[adilei]

It’s not my Wifi - it’s the cellular network. Hence my confusion.

Thanks,
Adi
