Nextcloud - HAProxy Problem

Help
1

Good Morning,

I have mounted a NethServer that provides Nextcloud service and I want it to previously go through a HAProxy, that is:

Internet -> Haproxy (with Lets Encrypt certificate) —> cloud.mydomain.com/nextcloud

And I have several doubts / problems, the first is the / nextcloud, it is not possible to access directly via cloud.mydomain.com, second when the connection passes through the haproxy if I put cloud.mydomain.com I get to the nethserver page, but putting cloud.mydomain.com/nextcloud gives me the following error in the browser ERR_SSL_PROTOCOL_ERROR

Please if you can help me I would appreciate it, I already have everything configured and I just need to pass it through the reverse proxy / with certificate to put it into production.

Thanks greetings!

Hi @fgonzalez

please answer the following questions:

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:

I ran this command:

It produced this output:

My web server is (include version):

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

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):

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

My domain is: cloud.marinador.com

I ran this command: certbot certonly

It produced this output: The following errors were reported by the server:

Your command

is incomplete. Which authenticator did you use?

The SSL_ERROR_RX_RECORD_TOO_LONG is expected. That's the Grade Q - https://check-your-website.server-daten.de/?q=cloud.marinador.com - http on port 443, you don't have a working certificate.

That may not work, that Certbot is too old. Minimum 0.28 is expected.

Good morning JuergenAuer and thanks for your help,

At the moment it does not have a valid certificate in 443 because I expected to take it out in the HAProxy, it is pending to renew the entire HAproxy but at the moment I have several services working with this version of certbot and I have no problems, really the problem gives me when I try to access cloud .marinador.com / nextcloud, access cloud.marinador.com if you access without problems but it is not the service I want to expose, I leave the configuration of the HAproxy in case it helps …

Your haproxy isn’t the question, there is a correct answer of port 80 /.well-known/acme-challenge:

Certbot may not understand your configuration.

What says

apachectl -S

They really are two different servers,

HAPROXY ----> NethServer (with Nextcloud)

I leave the result of the command on the server where the Apache service (Nethserver) is

VirtualHost configuration:

There is no port 80 defined. So you run Certbot on the wrong machine.

You have to use the machine with that answer:

 http://cloud.marinador.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
46.25.72.130
Inline-JavaScript (∑/total): 0/0 Inline-CSS (∑/total): 0/0	404

	A
Not Found
Visible Content: Not Found The requested URL /.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de was not found on this server.

And your complete command is required so your authenticator is visible.

Good again

I’m sorry but I do not quite understand you, you say that port 80 is not defined in the Apache server?

Greetings!

See your output, there is no port 80. So it's the wrong Apache or the wrong machine.

But checking your domain an Apache answers port 80. So that may be another apache.

If Certbot sees the wrong Apache, the validation can't work.
