Greetings friends of Satoshi!

I have been running Bitcoin Full Node 23.0.0 over Tor to do my part to contribute to the cause. I am using Windows 11 on a freshly formatted PC with the Bitcoin Core data on an external USB 3.0 SSD. Everything has been working fine with little stress on a 2 year old PC.

Recently I decided to configure a newly formatted Nano S hardware wallet with Electrum Wallet 4.3.2, connecting it to my Node via Electrum Personal Server 0.2.4.  I connected the Nano to Electrum wallet successfully, displaying a fresh set of wallet addresses. I then copied the Master Public Key to use in the Electrum Personal Server (EPS) config.ini file, as well as other settings I've researched for that and bitcoin.conf (Bitcoin Core).

I ran EPS, connected to Bitcoin Core, and it imported the Nano S wallet from Electrum, which became the first Bitcoin Core wallet installed on the Core. Next I validated the wallet addresses visible in Electrum Wallet matched those on the Bitcoin Core. However, upon attempting to reconnect the Electrum Wallet to the EPS, I have no longer have a connection between them. I should note that it was recommended to launch Electrum so that it only connects to localhost on EPS server port 50002. "C:\Program Files (x86)\Electrum\electrum-4.3.2.exe" --oneserver --server localhost:50002:s

Without that modification, Electrum sees external servers that it can connect to, but not EPS on localhost:50002. With the modification, no external servers are available, but it doesn't connect, with localhost:50002 specified but greyed out. Here are the Electrum logfiles, which include the connection errors. I will also include the EPS and Bitcoin Node configurations below that:

Sorry for the long post, but I also checked if 127.0.0.1 was open to all internal apps, and even specified both Electrum Server and EPS apps as safe in Windows 11. If anyone can help get me through this, it will be amazing after two days pouring through Google, where Windows configuration content on a pure Windows implementation seems especially rare.

Thanks!

My cold storage PC is an old Dell Inspiron 4500, running Kubuntu 13 on a secondary drive, with the primary drive containing Windows XP which is no longer used. It was unplugged and sitting idle for over two years, but a few weeks ago I wanted to access a bitcoin from storage since there are more retailers that now accept Bitcoin. So I installed Armory on my new Windows 10 PC to use with the Watching Wallet I exported from Kubuntu.  I successfully imported the wallet, then as I waited for the blockchain to download, I foolishly decided to update the cold storage machine to Kubuntu to 14.04.

I have spent the last two weeks trying to get around an encryption component adding in the upgrade that made my host system unaccessible. I tried several remedies, but I have no way to access the cold storage wallet. I was foolish not to make a fresh backup beforehand, as the paper backup I originally made a few years ago is nowhere to be found, and the digital backup I made was on a USB stick that my daughter found and overwrote. In this process, I was also surprised to learn the sad news that Armory is "at the end if its road", so am I totaly out of luck, or can the Watching Wallet somehow be used to retrieve them into a new Wallet solution?

Thanks!
Janx
