I'm getting the following message : Couldn't get a socket, try again

I need to connect lightstreamer to a certain domain, lightstreamer can't connect at all, I have tried to setForcedTransport to different protocols, non of them working.

However, I can open the lightstreamer page from MS edge, chrom-Incognito.

Why I can't connect from java at all????????

Here's the log

Hello,

If you need to pass through a proxy, you have to set it explicitly by using the method ConnectionOptions.setProxy.

For example

client.connectionOptions.setProxy(new Proxy("HTTP", "myproxy", "3000"));
