HTTP streams stopped working after upgrading to 2.6.101 / 3.1.2


Hello everyone,

My HTTP streams stopped working after upgrading to 2.6.101 / 3.1.2 and I cannot get them working again. I’ve tried deleteing them and re-adding, but no luck. The agent will not get past the TEST, it only sits there and the spinner spins.

I can see the video perfectly using the same link in a browser.

Any thoughts?


Hi Jason,

What version were you on before? Can you try the following procedure:

  1. Backup all files in [install_dir]\etc\openalpr and [install_dir]\var\lib\openalpr
  2. Uninstall OpenALPR
  3. Reboot
  4. Install the latest software to the C:\OpenALPR directory
  5. Copy the files back over var/lib and etc/openalpr
  6. Restart the OpenALPR Agent and OpenALPR Link service


Hey Matt,

I am also facing the same problem though on ubantu… I have installed, reinstalled, booted and rebooted again again and again but the video stream are not passing the test step and get stuck up after that.
One strange behaviour the oplr agent goes of by itself the moment i am changing the tab.
when i look the the results it says no option to access -



On the Alpr configuration utility, what do you see on the test step when you click the “Details” button?

Can you post the content of the /var/log/alpr.log file?
