Due to a February 2020 update to Chromium, the codebase for many browsers (Chrome, Firefox, Edge), non-secure (http) streams no longer play on secure (https) sites like radiocostarica.net, radionicaragua.net, and other sites in our family.
We are working with our streaming partners to have their content play on these browsers in the future. For more information on Google's Chromium update, please see this blog post.
