hello -

i found many excellent replies to this issue:

websocket connection to .... failed: Error during WebSocket handshake: Unexpected response code: 400"
however, none of the solutions seemed to talk about ssl websites. according to a reply on StackOverflow:

https://stackoverflow.com/questions/41381444/websocket-connection-failed-error-during-websocket-handshake-unexpected-respon/48096141

i was able to piece this together:

Quote:
.htaccess:

RewriteRule ^newPage/ https://mydomain.com:8010/[P,QSA,L]

RewriteRule ^socket.io/https://mydommain.com:8010/socket.io/ [P,QSA,L]

httpd.conf:

# 2019-01-15

LoadModule proxy_module /usr/lib64/httpd//modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib64/httpd//modules/mod_proxy_http.so
LoadModule headers_module /usr/lib64/httpd//modules/mod_headers.so
LoadModule deflate_module /usr/lib64/httpd//modules/mod_deflate.so

ProxyVia On

ProxyRequests Off

ProxyPreserveHost on

<Location /socket.io>

## https://stackoverflow.com/questions/41381444/websocket-connection-failed-error-during-websocket-handshake-unexpected-respon/48096141

RewriteEngine On

RewriteCond %{QUERY_STRING} transport=websocket [NC]

RewriteRule /(.*) wss://mydomain.com:8010/socket.io/$1[P,L]

ProxyPass https://mydomain.com:8010/socket.io retry=0 timeout=30
ProxyPassReverse https://mydomain.com:8010/socket.io
</Location>


so all I did was to take the StackOverflow answer and change apache module file locations, http:// to https://, etc. the problem seems to be solved, or so it appears.

any suggestions or improvements on this approach?
