Currently I started getting:
{
"code" : 400,
"errors" : [ {
"domain" : "push",
"message" : "WEB_HOOK channel unavailable for: {address=https://...}",
"reason" : "channelUnknown"
} ],
"message" : "WEB_HOOK channel unavailable for: {address=https://...}"
}
When I try to start watching Google Push Notifications. I have my domain verified and the url is available for Post Requests in the Internet. Notifications are just not coming to it. What might be wrong here?
