ISPConfig 3 Roundcube Plugin

Hi everybody, i've follow the guide "ISPConfig 3 Roundcube Plugin on Debian 9 (Stretch)" https://www.howtoforge.com/tutorial/ispconfig-3-roundcube-plugins-on-debian-stretch/, but i have no success in getting the plugins to work.

I've always get the message "Soap Error: Could not connect to host", my config.inc.php file looks like this:

Code:

<?php
$rcmail_config['identity_limit'] = false;
$rcmail_config['remote_soap_user'] = 'myuser';
$rcmail_config['remote_soap_pass'] = 'mypass';
$rcmail_config['soap_url'] = 'https://mydomain:2763/remote/';
$rcmail_config['soap_validate_cert'] = false;
?>

On the soup url, i've tried with the domain, one of the IPs of the server, even localhost, but i've always get the same message, and on the soap cert, i've tried with 'false', 'true', commented the line, and nothing.

Because of that i've been trying to find the logs related to the plugins, to have a more clear idea of why is no connecting to the host, but i haven't be lucky, so if anyone can lend me a hand i will appreciate it.

 

If you use httpS in soap URL, the host must have valid certificate. Have you verified the certificate is OK?
If the host does not have certificate, you must use http:// as protocol here.
Is the port number in soap_url correct and you have verified that is a working port in your setup?
If you use httpS and a valid certificate, I think you must use FQDN in the soap_url so hostname can be compared to the certified FQDN. Plain domainname in soap_url does not work.

 

@Taleman about your points:
1- The Cert i have is the self generated by the ISPConfig install, that's why in the soap_validate_cert i let the value in "false", but as a comment i also try it with "true", and commented.
2- About the port, during the install of ISPConfig I changed it, and i can access the panel with out problems.
3- About the FQDN, i check it and i have the same message.

@Th0m
If you mean go into my panel > System > Remote User, and create a user, yes i did.

 

@Th0m If you check the tutorial, they put the closing of the php code "?>", that's why i add it to the file.

With the http i think is not possible because if i try to access the panel without "s", i receive an error message:

Code:

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

So if this simple test didn't work, i think it wont with the remote option either.

About the checkbox that you mention, yes I enabled it, and is still enable.

And I think the problem i've got is because i'm using a self certificate, instead of a valid one like LE or other, but i'm not quite sure about this, that's why originally i was asking if someone knows where to find the logs of the plugins to check if theres a better description os the problem.

 

I did that and i still have the same error.

 

I did that, and it's working, at least the plugin to change the password, now i'm going to check the others.

 

I used the Howtoforge Tutorial on December to install the plugins on host running on Debian 10.x. The plugins are working.
I can not see what significant setting is different on my Tutorial compared to the one @Th0m posted a link to.

 

The tutorials are like print publications, they can not be updated after publication. Sorry.
