SoftEther VPN Problem

I am using SoftEther VPN on Raspberry Pis

I used K6OZY videos and got all up and running, made some Qs etc. Ran for 3 days non stop, then went belly up after slowing RTT to 500 msec. Have 6500 in Maine on TimeWarner/Spectrum cable with R7000 router and Maestro in Mass on FiOS with action Tec and also tried R7000. A few strange messages on action Tec led me to suspect FiOS so brought in Charter/Spectrum cable after no support from Verizon.

SoftEther apprears to connect fine and shows all normal signs including ip lists. maestro sees radio, and SW versions of Maestro to choose from then hangs at just the Smeters on the screen. After 5 minutes it will allow the MENUs to be chosen and it has both 6500 and Maestro IPs on the two networks. But shows no network activity.

Tried SSDR on the computer in Mass. and it sees radio but hangs after selection.

SSDR on the computer in Maine, via VNC, works fine no problem.

Talked to TimeWarner/Spectrum and they say no problem or reason VPN wont work.

Of course, Port Forwarding on the Maine R7000 is fine.
BTW I switched to the R7000 after the Cisco didn't work

I have no idea what the 6500/Maestro should be trying to do at this point, but what ever it is, it isn't doing it.

ANY HELP appreciated. It was great for 3 days and I would like to get it back going again.

BTW, in the course of trying to find a solution I have reloaded and resetup both Raspberry Pis

Thanks
