when you get a new version are you unzipping into a new folder or overwriting the existing folder? try extracting to a new folder then copy the config folder over then start the new app

I just edited my post. I was running a different alpha with the prior post.

I'll try running fully fresh again.
 
(fresh install) -- Version 3.14.3-alpha1 logs. These are the docker logs which seems to have more info, specifically "System.ArgumentException: no metadata found for given date range".

there should be more information after "System.ArgumentException: no metadata found for given date range", did you overlook that line?

awesome, so the openalpr agent is returning an error code but no message about what is causing the error, classic lol

Here's the log from the Windows client:

1625626941725.png
 
1625627293904.png
 
The "Earliest date epoch: 1624761037594" is shown on the OpenALPR Local Webservice Diagnostics page. Can you use that as a reference? Check from that epoch to the current epoch and then see which are missing from the DB? I'm guessing it is somewhat done in that manner.
 
That's pretty strange, if there are no plates it should return an empty json array.. ok try v3.14.3-alpha5 i've removed the exception when the agent doesn't return the proper data, maybe you have a bad date range or something.. it will try them all now

Still a no go.
Code: 
07/07/2021 11:33:56 +00:00 An exception was thrown attempting to execute the error handler.
07/07/2021 11:33:56 +00:00 HTTP "POST" "/alerts/pushover/test" responded 500 in 8.4912 ms

07/07/2021 11:33:56 +00:00 Failed to send alert via Pushover.

Not sure what the deal is. I've made sure the API and User key are correct. I can send tests from the pushover.net website to those keys so I know its working properly on their end. That VM that runs the container has an internet connection. I can ping api.pushover.net

Edit: Actually Docker containers don't have internet access by default do they? I think that is the problem...

Edit2: Well I guess it does have networking access as there is no way I could be using the service currently without it. Here is what my Docker Run file looks like:
Code: 
#!/bin/bash

docker run -d \
--name=openalprwebhookprocessor \
--restart unless-stopped \
--net=bridge \
-v /home/user/webhook_alpr/app/config/:/app/config/ \
-p 3859:80 \
mlapaglia/openalprwebhookprocessor:v3.14.3-alpha4

I'm at a loss.

If you are getting a 500 error you are reaching the pushover server but the call is failing.

Can you PM me your user key and api key? i'll try troubleshooting on my side.
