Some routers are not able to route packets from the internal network back to the inside when adressing the external interface.
Things might be working fine from the internet, while you cannot access the 'real URL' from within your own network.
To solve this problem, you should
- let us know what URL you're using
- when it's supposed to be up (date, time and time zone)
- what router you're using
A simple way to verify your URLs can be reached from the internet it to check the 'Listed' checkbox before starting the web server.
If your URLs cannot be reached, you will get an error message.
If all is ok, you will see your camera listed in the
