Hi there, regarding the 500 error, how do you get it? Do you try to reboot the device or does it appear on a different way? The test\_dockerhub is a false alarm from our side, and we are working on it. You can find the relevant GH issue here [https://github.com/balena-io/device-diagnostics/issues/249](https://github.com/balena-io/device-diagnostics/issues/249). ---

Hello Anton, Im sorry I am not sure I understand what you mean about the public url, did you see that error when trying to reach the device publics URL? One thing which would help us understand what is happening is navigating to the diagnostic page and downloading the diagnostic report for the device. That should contain logs for the supervisor and other services which can help us debug these kind of issues ---

I am having the same error. I am using the balena cloud and motioneye to get this working but when I click on public device url and then the url it generates, I get this error. How to fix that? Below is the message I get. # Error accessing device We encountered an error when reaching this [balena.io](https://balena.io/) device: UUID 7e3ca05ece739bcb2d0xxxxxxxxxxxxxxx `tunneling socket could not be established: 500` One possible reason is because nothing is listening on port 80 on the device. thanks. ---

Hey Javed, `One possible reason is because nothing is listening on port 80 on the device` Yes, this is the reason. You will need a service listening to port 80, for the device URL to show anything. Phil ---

I used the instructions as mentioned by bkjaya1952 above. I am using pizerow instead of pi3. I used the motioneye and pulled from docker per the instructions. I get this error when I run it using the device public url. Thanks, ---

Hi Friend I didn’t try for pi zero . When creating an application and device , select the correct balena image compatible with pi zero. I have downloaded the balena image compatible with raspberry pi 3 .If the correct image can’t open the public device url , It is better to seek the assistance of balena team.To start the motionEye ,You will have to start motioneye container by running balena start motioneye or balena restart motioneye On the balina terminal . ---

Hi there, take a look at this [thread](https://forums.balena.io/t/motioneye-security-camera-setup/3903) for additional inspiration. the project it refers to is a little out of date, but it should give you a hint on how to make the software listen on port 80 so that device URLs will work automatically. Alternatively, you can try [this](https://www.balena.io/blog/make-yourself-a-security-camera-system-in-30-minutes-or-less/) project, which is more up to date. ---
