MPPT 75/15 worked as expected for several months. Last week or so it will not connect with the Victron Connect app on my phone. As the app suggested, "forgot " the controller on my phone. Reconnecting asks for the code displayed on the controller. The only display is green/yellow/blue LEDs. Using the default 000000 will try several times to connect before saying to forget the controller and reconnect with 000000. Endless cycle...
Attempted PIN code reset. That asks for the PUK code on the sticker. Entering the code on the sticker results in a message to wait 30 sec and try again. Waiting 30 or more sec and trying again gets the same message. Another endless cycle..
Behavior is the same with the Victron connect app on other devices.
The LEDs say the controller is still working. I'd still like to monitor it and the batteries, but the app is now worthless.
Any ideas? Thanks.
