Thanks for your reply, push alerts are now working, however geofence seems to be intermittent. Ever since I installed Nougat on my Android devices they have been acting strange, connecting to wifi and updating location. So it may just be the nougat update causing me problems. I have updated to 4.5.3.7 yesterday, reset geofence on android devices.
Do you get the same message in blue-iris as in my first post?.
This is how my Stunnel is configured.
