Can't setup Database Connection

I'm trying to remote connect with dreamweaver to a raspberry with mariadb, but for some reason webassist "Dynamic MySQL" and "Dynamic MySQLi" do not connect and result in an error. I have tried 192.168.2.30:3306 and without port but the error keeps returning. I can remote connect without a problem with Navicat and MySQL workbench.

Do you have any suggestions?
Do i need to delete configuration files?

It may be an issue with the site definition in Dreamweaver. If you export and send me the site definition you are using (privately) then I can try to reproduce the problem and debug it. My guess is that the problem is elsewhere in your site definition.

Hi Ray, thanks for the fast reply and willing to look into it.
I have attached export DW site definition including local paths

You have your website url set to: http://printserver/

That isn't a working domain. It needs to be able to connect to the website in order to test and retrieve data from the database.

It's a local server and not a public server

Are you sure the local server is set up properly? I can't really test because I can't access it, so for me that is the issue.

Are you able to FTP to the server without problems? Does Live view work for your pages? If you create a page on the server with:

<?php
phpinfo();
?>

Does it appear to have MySQL installed?

Yes, i'm 100% sure webserver is working and installed with all webservices and modules (apache2 + vsftpd + php + mariadb) and i can use a different mysql client without a problem because this is a server behind LAN and not a public server.

The way dreamweaver tests a connection is this:

1) It uses the testing server settings to transfer files to the _mmServerScripts folder
2) It uses the url specified in the testing server to post data and access the files it uploaded which return xml with the results

The error you are getting means that it can't access the files once uploaded. Can you see the _mmServerScripts folder in the file system and confirm they were uploaded properly onto the testing server?

If you manually browse to one of those files using the url and appending the folder and one of the file names can it be accessed? For some reason Dreamweaver is unable to browse to that file. Is it possible it has a firewall that is blocking dreamweaver's browser?

Anwser is yes, mmServerScripts are uploaded to remote server.
Dreamweaver can access the ftp without a problem.

Can you browse to one of the files in the mmServerScripts folder in a browser?
