Heya @tysonosore,

Ensure that your Socket.IO version is compatible with the Node.js version you are using. Sometimes, outdated versions of Socket.IO may not fully support the latest Node.js or SSL/TLS protocols.

Additionally, how did you configure your HTTPS? Can you share your code so that we can see if there are any issues with it?
