ENHANCEMENT: Find an open port if 8080 is in use

[NealHelman]

It has been requested that the wallet find an open port if the one it's trying to connect to the core on is in use. This would require both the core and the interface checking to see if the port they're trying to use to communicate is in use, finding an open port, and negotiating that open port with each other (core and interface).

We have had at least three support sessions where the resolution was achieved by switching the SSL port in the wallet from 7080 to 8443. Can that be set as the default in subsequent versions?

I think I found the Base Way to Achieve this without any extra Code, but the Code Back-End might need improved!

Adding the Line to NEXUS.CONF file

listen=1
listenport=0

There seems to be 2 Ports within Core already for Blocked Default Port, but listenport needs to set to Auto Port to find a new one other than 7080!

Port 8080 is Non-SSL port and has been Off within Nexus Interface for 1 year maybe IDK!

I got Nexus Interface Acting (so far) Great Staking without the usual Stake Blocks failing or Forked Blockchain using
listen=1
listenport=0

This is the 3.1.5 Tritium so it's Old Version without the newest Sync Node! But I Synced the Blockchain using Compiled Nexus Core!

I was looking within the Code where it Default Writes/Creates the nexus.conf file on 1st Startup only after installation of Nexus Interface Wallet

But I didn't find where it's located searching!

But if Nexus Interface added those 2 lines as DEFAULT for 1st Install of Nexus Interface it should FIX the Staking Issues

Stake Nodes sometimes were breaking in the Past to verify or know how to verify issues that forced breakage of the blockchain while Online 24.7 for certain users, including "myself" myself being the Only Source of this knowledge while TESTING different aspects of the Software and finding it's KNOW-LIMITS

but this is KNOWN New NOVEL Software and is understood to be Verified Secure, these aren't Backdoors, being Solved, but Basic Software Code Repair and Upgrades that Try to Eliminate most of the Spam Connection type threats to Blockchain Security Overall using HardCoded Code that Runs Nexus Nodes!

And most Common People wouldn't understand it if knot patient enough in Life to Learn and Listen!

Adding the lines to nexus.conf

listen 1
listenport 0

Still Working Great even with the 3.1.5 Tritium Interface 👍
