client[socket.js]

socket = io('myip:8085', {     rejectUnauthorized:false,    autoConnect: true,    reconnection: true});

index.js:83

   GET https://myip:8085/socket.io/?EIO=3&transport=polling&t=P0788Hq net::ERR_SSL_PROTOCOL_ERROR

i applied ssl spirng server and netty socketio server both.spring server serves static files and dynamic files. the files served correctly. but when client socket connect error::ERR_SSL_PROTOCOL_ERROR index.js:83

   GET https://myip:8085/socket.io/?EIO=3&transport=polling&t=P07G5ka net::ERR_SSL_PROTOCOL_ERROR   how can i fix it?

i try remove socketio server https. but Mixed Content The page at ' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint ''. This request has been blocked; the content must be served over error i added html code but the error exist.how can i apply ssl to socketio server? is netty socketio's corundumstudio.socketioserver is not accept p12, jks certificate files? or there is othere way to apply ssl?

my nettysocketio version = implementation 'com.corundumstudio.socketio:netty-socketio:2.0.9'client: socketio-client = 2.5.0
