I really hope you are correct but I have already tried adding https in my connection settings. The ftp part works and it already did work, but when I try to look at a database or test a recordset, I get a popup message in DW that says my SSL Certificate isn't installed correctly, even though I know it is. I assume that's DW seeing the TLS 1.2 and not knowing what to do with it.
Although I haven't found anything official, I did find this on an adobe forum. It kind of reads as an official confirmation since a "staff" member provides a work around of using another ftp program. Of course, it doesn't mention the behavior panel specifically so it's not an exact match to my problem.
This forum is mostly about yahoo hosting where they posted a notice that once they upgrade their servers to TLS 1.2, Dreamweaver (doesn't even mention a version number) won't work to ftp.
I will keep trying though. You gave me some encouragement that it might still work.
Oh, I should also mention that I did whitelist my IP address in the cPanel under SQL Remote settings and that didn't make a difference. Maybe I am missing something else. I will keep trying.
