Several weeks ago my push notifications stopped being delivered. I cannot see why as I haven't made any changes (apart from updating PRTG). Here is the current situation:
PRTG version: 126.96.36.19921 Mobile client: Android v 188.8.131.52
My mobile is registered under the notification contacts.
I did try to remove and re-add the notification contact. I did try to uninstall and re-install the mobile app.
When checking the logs I find this around 2-3 minutes after the notification should've been sent:
Error sending "Push Notification": Unknown error response (Sensor/Source/ID: 2068/2066/1)
I should mention that I am running PRTG through an IIS proxy as described here: https://kb.paessler.com/en/topic/44613-using-windows-iis-as-ssl-proxy-for-prtg#reply-234049
Does anyone have any ideas?
