Issue with certificate

So the issue is this I had my server accesible at:

and I could access my owncloud instance. But I wanted to have an https certificate for security.

However after running lets encrypt it now times out in the browser and I get the below error code when I try to verify it. Even if I just use the normal http which worked before. Any ideas?

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:

Used Let’s encrypt from dietpi menu.

It produced this output:

Error code 1:
An unexpected error occurred:
Error creating new order :: Cannot issue for “”: Domain name contains an invalid character

My web server is (include version):

lighttpd/1.4.53 (ssl)

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

Dietpi - Latest version : v6.31.2

My hosting provider, if applicable, is:


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


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

Well, Let’s Encrypt only issues certificates for pure FQDNs, not for URIs. Your “”“hostname”"" contains the path /owncloud which obviously is part of an URI and not part of the FQDN. You should try to issue a certificate for just without the path part. How this is achieved through the DietPi menu? I don’t know, could even be a buggy implementation from DietPi’s part.

Also, the reason why your Owncloud is “down” is because a redirect from HTTP to HTTPS is in effect, probably installed after you succesfully got a certificate issued yesterday. It seems your port 443 — required for “basic” HTTPS (without specifying a non-standard port) — isn’t open. Could be a NAT router without the proper portmap or a firewall which has port 443 closed.


It was my firewall setup and all is running well now.

Initially I thought it was because I hadn’t included /owncloud/ but it was my own idiocy.

Thanks for your help @Osiris
