thanks for answer. I have port forwarding used to my web server port 80.
So it is not possible that Fronius acts as a server on the same port.
Is it possieble to define some other port in Fronius ?
Acts Fronius as a web server ?
after change of my router for Mikrotik hAP AC2 the communciation to solarweb.fronius.com was broken.
I need help to write some rule(s) in /ip firewall according Fronius documentation.
Thanks for help.
