Please help !
I have tried static IP , remove and reassign myvolumio account. All my effort is in vain. !
Start by sending a log as we have no crystal balls, don’t lay tarot cards and can’t predict the future.
If you set a static IP and you can’t connect to internet (that’s why you see plugin page is blank) it’s very likely that you’ve entered a wrong Gateway or netmask value.
Try with using Auto IP, if it’s solved, then that’s your issue
Downgraded to 2.917 version… Now it is working like charm 
Seems something is not correct with your Volumio account
