I don't remember having to click on "Use SSL" when I tested this on my own setup back when I was writing this thread. Maybe it was already turned on from before or the software did it by itself after a restart. I also don't remember seeing error messages.
I see what happened here:
He must have disabled that "
Use SSL" switch beforehand (
from his old settings or something else) that's why he had to enable it when he followed your instructions.
On the other hand (
at your end);
You do not remember having to tick that settings and your test worked right away because it's switched-on by default.
Including a short note should prevent rare instances like this.
