I have a Neuron running a Mervis program for almost 2 years, together with a web-hmi page.
It worked flawless all the time, but today I wanted to add a variable to the webinterface and after that the webinterface dropped dead.
I already removed the variable and restarted the neuron a few times, but nothing helps to revive the webpage. All variables have a red dot and values.cgi keeps responding:
{
"ver": 1.0,
"code": "error",
"msg": "No variables from request available. Check device parameters and availability."
}
