I own a SmartSolar 75/15 without any issues so far, with the device or with the Victron Connect App.
Lately, I can't connect my phone (or another phone, both Android) to the App. The device appears on the list, but when I click on the device, the progress bar goes to 20%, then back to 1%, and so on until the message "unable to connect blabla" appears.
I've also tried to reset the PIN with the PUK code, and still an errors shows saying unable to reset the PIN number.
On top of that, the device seems to work correctly as the bulk blue led is steady while the panels are at sun.
I've of course installed/uninstalled/cleared cache of the app several times, and the latest version was used.
Thanks for your time,
