Can't renew my certificate, “ Error getting validation data”

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., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: many, e.g. certbot renew,
certbot renew --apache (which he didn’t recognise)
certbot renew --http
certbot to create a new one

It produced this output:
The server could not connect to the client to verify the domain :: Fetching[...removed...]: Error getting validation data. Skipping.

My web server is (include version): Apache2 (see below just apt-get updated but how do I find the version?)

The operating system my web server runs on is (include version): Raspberry Pi, Raspbian just updated (can’t find the number

My hosting provider, if applicable, is: (Pi is here at home)

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): I don’t know? I think not, I have SSH access?

First of all thanks for the awesome service, Let’s encrypt provides, I’ve had a certificate for a while now (it expired May 4th) but I am unable to renew it since May 5th (missed to do that before it ran out).

I tried a lot and read all Error getting validation Data threads available, tried deactivating my redirect to https in the apache config,…I don’t have a clue anymore what to look for.


It seems that your http port 80 was either filtered/not open/ misconfigured. Since only port 443 opens @port scan.

Please check your port settings since http-01 need to connect to http port 80 first then (can be redirect to https port 443).

Thank you

Thanks – a little sad that such an easy note fixed it, but I wasn’t aware, that renew needed port 80 nor that I actually did not open port 80. As soon as I did, it worked :slight_smile: Thanks again!
