Pavlovia and AWS

URL of experiment:

Description of the problem: We are having trouble accessing an AWS EC2 server link from within Pavlovia. We have a Python-based server that we are running on an EC2 instance (w/ HTTPServer). We have tried pasting in the EC2 instance public IP address in our Pavlovia-based experiment; however, it seems that we need the EC2 instance to provide an “https” link rather than “http” (http doesn’t seem to be accessible w/in Pavlovia). Has anyone successfully set up an EC2 server to work w/ a Pavlovia experiment? If so, were there key steps you took in making sure the EC2 address is accessible from your Pavlovia experiment? Thank you!

Below is an example error we get when using our http EC instance from Pavlovia. Thanks!
