Unable to connect to Monero node IP, haveno fails to start
I just downloaded Haveno appimage for Linux from RetroSwap. It initially started up by connecting to the default Monero network nodes. Then I put in the IP address of my in-house node and shut down Haveno as instructed. Now it won't finish starting up. It says, "Connection failed to Monero Mainnet" and, "Haveno network peers: 13." I have verified that the Monero node at the private address is up and running. I've been running this node for years.

The Monero wallet connects to it beautifully.

1) How do I get past this point?
2) What did I do wrong, that caused this impasse?

Thanks.
