I'm having trouble working with AWS ElasticBeanstalk with NodeJS environment + Socket.IO + SSL for our messaging app.
I'm already running in circles trying to fix the issue but I always ends up to a Websocket handshake error (504 GATEWAY_TIMEOUT).
AWS Elastic Beanstalk Load Balancer configuration:
ELB security inbound rule
Instance's security inbound rule
Response error
Front end code
Thanks in advance. Any help is highly appreciated!
