Welcome to IntelliConnect. The advantage and weakness of that system is that everything goes through a Pentair server. That can be a big help when you need tech support, but it also makes your system vulnerable to Internet issues plus local Wifi issues. If either you or Pentair has an Internet outage, you lose ability to control the equipment through the IntelliConnect. The good news is that Pentair's connection has been pretty reliable. However, if anyone is tinkering with your Internet connection, changing wifi key, rebooting your router, or anything that interferes between the IntelliConnect and Pentair, your are temporarily out of service.
If everything is up and running now, then it could be Pentair's problem. Most things you can handle manually, as the connection is not necessary for the equipment to run, only to change. I have had one time a loss of connectivity with the IntelliConnect, but it was when I changed my wifi key. In that case, I had to reconnect again like it was brand new.
