Electrum wallet, no connection

Hi all, I hope someone can help me out here.

I have the (portable) electrum wallet for Syscoin version 1.0.0 and it does not connect to the network. I opened port 58882 in my router, tried to connect using Tor and even tried different computers.

The version of the wallet on the website Electrum Syscoin Wallet van also not connect.

So far no luck. Do you have an idea of solving this? I don’t know what step I am missing. It used to work, I sent SYS to it a few months ago.
