When I try to “pilot in browser” (orange play button with JS logo) on my Mac, I keep getting the error below. It looks like there is an issue with SSL certificates potentially being expired.
I have tried this in both v2025.1.0 (py3.10) and 2024.2.4 (py3.10), and on multiple macs. This happens regardless of the experiment file I’m working with, and with multiple Pavlovia experiments. I am able to connect to Pavlovia fine otherwise (e.g. via the web or via the Pavlovia buttons in the builder toolbar).
Any help would be much appreciated.
