WebSocket is closed before the connection is established

[ganesh_karale]

Hi, We are trying to connect sslvpn web mode and accessing website using https.

After opening that website it redirects to other url which uses some custom port and website is not opening.

We checked network logs in the browser and observed that it shows some other port and error "WebSocket is closed before the connection is established."

Same thing is working fine if using forticlient.

It looks like websocket is not supported in sslvpn web mode.

Can some one please guide.

Regards,

Ganesh

hi @ganesh_karale ,

It sounds like an unexpected behavior.

Please open a ticket with Fortinet TAC and share the configuration along with the screenshot of the error for further investigation.
