ELK EZ8 install - pulling out my hair with ethernet access

This is my second house and my second Elk install.
 
I am at the point where I think there is a hardware issue.
 
I have tried various methods to access the panel through ethernet and it is not working.
 
I can "see" the ethernet on my network.
I can ping the ethernet.
ElkRP can find it
My ISY 99 can see it.
 
I cannot connect to it.
I tried direct through my network.
And I made up a crossover cable and connected direct.
Also had a switch laying around, tried that also.
 
I cannot access the ethernet address direct from a web browser either.
 
My serial number is a sticker on my panel and I confirmed it with my keypad.
I am using the RP code from the manual.

Are you trying to connect to it using Windows 10?  There is an incompatibility between the SSL/TLS security protocols supported by Win10 vs what the M1XEP supports.  To fix this problem, you need to upgrade the XEP to the latest firmware.

I tried Windows 10, Linux with Wine.
My ISY cannot even connect to it...
 
Not sure that is the reason.
 
I guess I try to buy a COM/USB cable now?

Is there a log or something that I can see why it is not connecting?

If it is the Win10 thing the fixes are to either upgrade the M1XEP firmware or enable the non-secure port. The ISY also requires the non-secure port. Also I am not sure if RP will run under Wine or not.

I am not sure how you would do either an XEP firmware upgrade or configure the non-secure port unless you can get connected initially with RP. I don't see a way to enable the non-secure port via the keypad. You may need to find yourself a machine with Win7 or XP. You could maybe load a copy under a VM.

I tried RP in VM also.
I can see it, I just cant connect.
 
How can I tell if it is a setting or a password issue?
 
I have a Windows 7 machine at work I will bring home and try.

The error I get on Win10 is "Could not initialize Secure Connection", I think if it is an access type issue you will see it connect but fail on the "Verifying System Identity" part.

I brought my Windows 7 machine home from work and everything worked perfect.
It is odd that my Windows 7 on Linux box would not work.
 
I am still showing issues connecting to ElkRP on my windows 10 machine.  Says my code is not valid.
I did all the firmware updates from the Elk site.

Are you referring to the RP access code?

That is correct
It is the RP access code.
 
I can connect all the time with Win 7
I can now connect with Linux box running Win7.
It won't find the device, but it always connects.
 
I am using the default RP access code.

Linux box running 7? Explain that configuration more....might be going out on a limb, but usually Linux is used as the OS in the boxes instead of driving another OS

Linux box works fine.

It is the pure windows 10 machine that hs the issue.
