Why am I getting an SSL error when accessing the API?

It sounds like you are using an HTTP client that doesn't support modern HTTPS protocols and ciphers. Try upgrading your HTTP client to a newer version.

Note that this may happen even though you've previously been able to access the API. This is because we sometimes remove support for older SSL protocols and ciphers that are no longer considered secure, to comply with best practices. To avoid problems, we recommend that you regularly upgrade your  HTTP client - for example, at least once per year - to ensure that you are always using a relatively new version that supports modern protocols and ciphers.
