Hi Clay,
With some delay I reply to you and thank you for your help.
I managed to install Local but it was not easy. It took many days. The problem was as well with the SSL Version that my computer was not able to read.
Now, it works, It bugs enough at the beginning when I click on Admin or View Site. Usually I have a Bad Gateway page from the browser. So I have to restart it quite each time I use it. And then I can connect when in Admin or View Site.
Glad you got it up and running! Do you remember what you had to do to get it working?
Sometimes after just starting a site in Local, you’ll see this error due to PHP-FPM not being fully started. The error will usually go away after 20-30 seconds or so.
