DW CS6 and TLS 1.2 will no longer work together in most cases
It appears that DW CS6 will no longer work with servers that are TLS 1.2. A few days ago, some of my sites wouldn’t connect through DW, to the databases. I finally figured out that those that would not connect, were the sites that I had SSL certificates configured. It turns out that at that time my server host upgraded their servers to use TLS 1.2 to get ready for the requirements of PayPal, UPS and a few others.
After some research, I found some confirmation that DW CS6 will not work with TLS 1.2.
I realize it’s an old version of DW and I should try to upgrade to CC but I kept putting it off because of various issues I read about it with regards to DW CC. I even found a post that said that the 2017 version of DW CC wasn’t working with TLS 1.2. I assume that has been fixed by now but wanted to make sure. Has anyone had any issues or solutions for any of the DW versions?
Again, this is only affecting sites that are hosted on servers that are TLS 1.2 and don't have TLS 1.0 or 1.1 enabled and I believe only affects sites that also have an SSL installed. This doesn't break your site, it just makes using the behavior panel impossible. At least, that is my experience so far.
