I cant connect to the 2.5.4 wallet. I tried different nodes. I even used the top nodes on Iota.dance/nodes. I even checked the console. These are the outputs:
How can I fix it?
If you do not own this server, there is nothing you can do other then contact the server owner, then choose a different node to connect to.
CONNECTION_REFUSED error means that the packet was properly forward to a host, but there was not a process bound to the port on the other end ready to accept that packet.
If this is your server, simply put, IRI is not running.
If this is the same error presenting across every node you try, you should check your local firewall.
