This means it is not my ISP, firewall, proxy, or windows machine.
Is this going to be fixed on its own later? Do you know?
In case it does not connect can I recover my XDN?
Your XDN is fine. You can download the daemon (darknoted) and run the GUI wallet from daemon.
On your GUI Wallet, take a look at Connections
You will see connect to "local darknoted"
load your Daemon, you may have to download the blockchain which could take a minute
wait till its fully synced and load your GUI wallet and under connections select connect to "local darknoted"
This happens from time to time and the remote connection needs to be reset. So not really a development problem, things just need to be reset every now and again
