CS6 suddenly stopped connecting to server

[LouieCypher]

When I try to upload pages using Dreamweaver's FTP I get the message:

I have checked with my service provider and there are no problems, I have also successfully conntected to my site using another FTP so I know the credentials (password etc. ) are correct.

It was working Fine yesterday

Something changed since yesterday.  What that something was is anybody's guess however.  Keep using your other FTP client while you continue to troubleshoot the problem.  I would start by creating a new site definition setting and deleting the old one.

It seems that my service provider has changed to TLS 1.2 protocol and Dreamweaver CS6 does not support this.

As DW CS6 is not updated anymore I don't see a quick solution to this.

Maybe time to look for alternatives 🤨

Keep using your dedicated S/FTP client to transfer files.  As you say Creative Suite is End of Life and no longer supported.   The alternative is to modernize your software and subscribe to the latest Dreamweaver CC which supports modern encryption keys.
