"Send Failed" from Samsung Note 4

Hello, thanks for your time and efforts on this project.

I am getting a send fail on the server I set up as well as the demo.

I will step through how I configured it.

Win7 server, installed Java and and server software. Opened all outside ports through windows firewall and even disabled windows firewall for testing purposes. I open traccar with localhost:8082 and it works with no issue. I create a user and Identifier. I download traccar app and install it on my Note. For the config of the app I input the correct identifier, I input the local IP of the server (192.168.1.250), I set my TCP port to 5055 and I tried the location provider on all 3 settings. I am connected to Wifi on the same subnet and can ping the server from my phone. I get the send fail message repeated. I tried port 5005 with no luck. There is no anti-virus on the server that would block this.

I tried on the demo server with the same ports as stated before with same "send Failed" messages.

Any help would be appreciated. Thanks.

Can you please check tracker-server.log to see if there are any messages from your device there?

Sorry Anton. Not sure where that log is located. I can't find it on a search of the server....

It should be where you installed Traccar server in the "logs" sub-folder.

Keeps saying unknown device?? Am I using the right port? I'm just testing with the android app and have port 5055 open.

Unknown device means that you haven't registered your device on the server.

I just created a device that says with the identifier 260458 and now it works...

Now it quit again and the log is repeating this message...

2015-12-22 15:43:58 DEBUG: AsyncSession: 772708488 destroyed: false create userId: 1 devices: 1

Please ignore any AsyncSession logging. It's not relevant to your problem. If you don't see any HEX messages in the log, it means that your device doesn't send any data.

Its working now. i just didn't wait long enough. :) Last thing. I accidentally deleted my map, how do I get one back? Thanks.

What do you mean by that? How can you delete a map?

On the server web GUI there is no map present. Its just a blank white page. My triangle shows up on it though. Wierd...

I guess you changed your map layer type in the settings. Just change it back to OpenStreetMap.
