After latest firmware update

Hello and Good Day

After latest firmware upgrade our In.Touch 2 swim spa control stop connecting to its server. It consists of two units that connected to each other can control the swim spa. The two units are paired and work with the app on LAN, but won’t work on the WAN. I know it uses Skype to connect to server. I contacted the company and they said server is up.
This happened after the latest firmware upgrade.
Anyone have anything on this?

Thank You

Do they connect via Wifi? A bunch of us are having issues with legacy wifi devices in this thread:

Hello and thank You for responding.

The two modules connect to each other via WiFi, but the home module is connected via Ethernet.
