Hi , already tested , doesn't fix
[C]Cors Issue , connect to remote server from webgl
I tried with and without header ( the settings are in the main post of the thread ), put logs before the connection request (directly in the colyseus code) to display the headers, they are empty or show only my settings set but nothing about "*, *", and my local wamp server has no CORS rules ... and fresh install
"*, *" means that there are 2 same headers in the request. there must be some settings or codes put them in the header I think.
