<![CDATA[[C]Cors Issue , connect to remote server from webgl]]>Hello with my team, we have decided to switch from version 0.10 of colyseus to version 0.14.18. We manage to connect with the remote server from Unity without worries but as soon as it comes to connecting to the remote server via the website with the WEBGL application, this one displays a CORS error that I cannot get to solve , the error seems to come from the header sent by the client :

alt text

I have an other error after that
alt text

Here is the code that allows me to make the connection:
alt text

The headers in Colyseus Settings are the same in the code previously mentioned.
The secure protocole is checked.

Hope to have some help coming here , good day for you !

And my local server ( from fresh install ) have no rule about allow cross origin but sent "," like the remote server
