Error code 501 response from push notification server

Hi good day.

I've noticed from 20 august that on my log appears messages like this constantly :

2024-09-07 11:47:21  INFO: Event id: 860896050915156, time: 2024-09-07 11:46:55, type: deviceFuelDrop, notifications: 1
2024-09-07 11:47:21  WARN: Push user 168 error - Operation is not implemented, or supported, or enabled. Raw server response: "{"error":{"code":501,"message":"Operation is not implemented, or supported, or enabled.","status":"UNIMPLEMENTED"}}"

I've not sure if it could be something to worry.

Thank you.

Are you sure you're using the latest version?

Hi Anton good day.

On Traccar Server is the latest. On Traccar Web is version 5.8, 'cause i'm still applying our changes to upgrade from 5.8 to 6.4.

And no code changes on backend?

Hi again.

No. On Traccar Server we have no changes.

Just as a question. If notificator fails to send notification via firebase with an exception or error code, this could broke connection between device and server?

Normally it shouldn't, but sometimes it could. Depends on the error.

This error usually indicates that you're using deprecated API, which would mean you have modified the code. But you're saying you didn't, so I don't have any other ideas.

Ok, many thanks.

Going to keep monitoring logs for any weird thing. I have a light suspicion that sometimes notification fails (NotificationToken changed or someting like...) and device connection brokes up, but i'm still not sure of it.

If there's something new i'll be updating here.

About deprecation, maybe this night i'll be reinstalling traccar again, to see if it fixes deprecation error.

Thank you so much.

Hello, I have the same problem, I am sure that I have not changed the code. App and server version is 6.4. Clean install today.

Notifications sometimes work, sometimes not.

Have you any idea what could be causing this? I am using official Traccar iPhone App.

Thank you for help.

Please try again now.

Hello, sorry for my late answer, now it is working perfect. Thank you. :)

Hi good day.

By my side, last error i've received from this, was yesterday sept 8th 2024 14:14 GMT -6. Since yesterday, i have no more errors 'UNIMPLEMENTED' on my logs, so i think it's fixed now.

Many thanks.
