Hi there,
I just installed hass.io and the let encrypt plugin
Now i want to add the settings to the settings box,
this is whats in it:
{
“challenge”: “https”,
“email”: “[email protected]”,
“domains”: [
“automation.mydomain.nl”
],
“certfile”: “fullchain.pem”,
“keyfile”: “privkey.pem”
}
But when i want to save the save button greys out.
Please help, i,m losing my mind here 
That usually means you’ve got invalid json or an issue with some of your inputs. Try validating your json at https://jsonlint.com/.
It’s hard to tell by what you posted since it’s not formatted correctly for the forums. That being said, it appears that you’ve got the wrong quote marks, but that could be the forums messing with formatting.
Try this…
{
"challenge": "https",
"email": "[email protected]",
"domains": [
"automation.mydomain.nl"
],
"certfile": "fullchain.pem",
"keyfile": "privkey.pem"
}
