If you are unable to connect you can click on Site-->Advanced-->FTP Log the next time you try to connect and let us know what error(s) you are receiving.
Also try connecting with a free FTP client like a FileZilla and see if you run into the same issue. This data can help us determine whether it is configuration with the FTP settings or whether the issue is with the host.
Thank you very much for your quick reply. I was able to connect via Filezilla and due to that Dreamweaver irritated me and I was thinking maybe the method of filling the credential could case the issue. Anyway, it seemed like the server somehow blocked the connection and I could solve this solution with placing my IP into a whitelist.
As Ben M said, use FileZilla. It's free.
If you cannot connect with FileZilla, then you know the problem isn't with DW. If FileZilla does connect, then you have an alternate way to upload files to your hosting server while you continue troubleshooting with DW.
WooCommerce does NOT connect with Dreamweaver in any way. WooCommerce is a 3rd party eCommerce platform for WordPress.
I was thinking maybe there is a solution to connect a proper DEV site with live preview and stuff. Is that possible via Dreamweaver?
Yes you can define multiple servers within DW. Just go to the Sites window and you will have the option to create it here, or also connect with a git repository if needed.
I managed to set up everything but I am not sure how to get live previews? In example if I modify some CSS files, or PHP or JS? It would be amazing if I can get a live preview straight in the browser. Is that also possible?
You need a local testing server to preview PHP files locally.
Is there any best practise maybe with a tutorial how to do that, since I never done something like that before.

Install a local server accoding to the vendor's instructions.
Go to Site > Manage Sites. See screenshots.
Move your local site folder into your local testing server's default web directory.
On Wamp the default is www. On Xampp and Mamp it is htdocs. For this demonstration, I'm using Wamp server for Windows.
Click the plus sign to add a new server definition and name it testing server.
Switch to Advanced tab and enter the server model : PHP MySQL
Post back if you need more help.
