Ask in the DW forum and provide more details like your server and connection.
Welcome to the forum.
Unfortunately, as Mylenium says, this is the Photoshop Forum. I will Move your post to the Dreamweaver Forum.
Your link and any e-mail subscriptions will follow.

Have you tried connecting with any other FTP software?
Filezilla is a good, free option: https://filezilla-project.org/download.php
If it connects and uploads without issue from FZ, at least you'll have a fully updated site while troubleshooting continues with DW.
If you can't connect, or a similar issue happens with FZ, it would rule out DW as the culprit.
