Timeout during connect (likely firewall problem)


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:elistovnik.uni-lj.si

I ran this command: certbot certonly --dry-run or certbot --apache

It produced this output: Failed authorization procedure. elistovnik.uni-lj.si (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://elistovnik.uni-lj.si/.well-known/acme-challenge/IqHwo5RBvgcKOGZI9lwWAr20kpnGp3kMC8jUVFN-2Sc: Timeout during connect (likely firewall problem)

My web server is (include version): Apache 2.4.29

The operating system my web server runs on is (include version): Ubuntu 18.04 LTS

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.28.0


Is your website firewalled? It’s not accessible from the external internet - https://letsdebug.net/elistovnik.uni-lj.si/22940


Hi @subjectx

your site is completely invisible ( https://check-your-website.server-daten.de/?q=elistovnik.uni-lj.si ):

Is there a blocking thing like a firewall?


I can access it, from my work and from home… Thats strange…

Let me talk with my networking guys first I guess.

Thank you for quick reply.
