Fail to connect on local Photon Server with WebSocket

Okay thanks a lot that's what I needed

But, now that I have been able to make the websocket connexion work on my local computer I have to make it work by SecureWebSocket to a remote server but I struggling a lot... I might be missing a step or something.

I have my Photon server runnning on a VPS which is linked with a domain name xxx.fr and I have followed the 5 steps from the doc: https://doc.photonengine.com/zh-CN/server/current/operations/certificate-setup

I generated a certificate by Let's Encrypt with certbot and combined the key and the certificate into 'server.pem'.

In the PhotonServer.config I uncommented the following lines:

"
<HTTPListener Name="*:[PORT]::Master" IPAddress="0.0.0.0" Port="19090" DisableNagle="true"
InactivityTimeout="10000" Secure="true" StoreName="Personal" CertificateNAme="escapegamelinky.fr"
UseMachineStore="true">
<Routing>
<Route Url="/+" OverrideApplication="Master" PeerType="WebSocket" Counters="false" />
</Routing>
</HTTPListener>

<HTTPListener Name="*:[PORT]::Game" IPAddress="0.0.0.0" Port="19091" DisableNagle="true" InactivityTimeout="10000"
AppDataInactivityTimeout="15000" Secure="true" StoreName="Personal" CertificateNAme="escapegamelinky.fr"
UseMachineStore="true">
<Routing>
<Route Url="/+" OverrideApplication="Game" PingEvery="2000" PeerType="WebSocket" Counters="false" />
</Routing>
</HTTPListener>

<HTTPListener Name="*:[PORT]::NameServer" IPAddress="0.0.0.0" Port="19093" DisableNagle="true"
InactivityTimeout="10000" AppDataInactivityTimeout="15000" Secure="true" StoreName="Personal"
CertificateNAme="escapegamelinky.fr" UseMachineStore="true">
<Routing>
<Route Url="/+" OverrideApplication="NameServer" PeerType="WebSocket" Counters="false" />
</Routing>
</HTTPListener>
"


And now when I try to connect with my client (in the Unity Editor) with the following params I get an error:

Params:
Use Name Server: false
Server: wss://xxx.fr
Port: 19090
Protocol: WebSocketSecure

Error:

And I openned the following ports on Windows firewall: 19090,19091,19093.
Do I need to open other ports?

Any Idea of what step I might have forgotten or done wrong?

Thanks
