Error "Terminating application due to critical License Error ACTIVE_INSTANCES_CAPACITY_EXCEEDED(104)"

[wujun]

I bought a Maker license from thingsboard and installed PE on docker(macOS v10.14.6, Docker v19.03.4). I followed the instructions to run the professional edition but I got the error "Terminating application due to critical License Error ACTIVE_INSTANCES_CAPACITY_EXCEEDED(104)" I DON'T know how to handle it. Here are
my log files: tb-license.log and thingsboard.log

Hello @wujun
By default a single license cannot be installed on two or more instances simultaneously. The key is bound to the instance ID (physical server/VM/container/image). 
Once you had activated the key, it was tied-up. Any other attempts to re-use the key would be failed if actual instance is not deactivated. ThingsBoard restricting any attempts to ‘mis-use’ the key.

In order to up and run your environment, please:

1. Stop TB service

2. Deactivate actual instance via the License portal (Subscriptions — Details — Manage instances — Deactivate particular instance)   

3. Delete instance-license.data file.

$ docker ps
you will get ID of your docker container, for example 09625616dba4
Connect to container console
$docker exec -it 09625616dba4 bash
You will see console bash, for example
root@09625616dba4:/#
Now run command to delete instance-license.data file
root@09625616dba4:/# rm -f /usr/share/thingsboard/bin/instance-license.data
Then deattach from container console
root@09625616dba4:/# exit
And restart container ('mytb' is the name of your container in default installation)
$ docker stop mytb
$ docker start mytb

4. Run TB service

Thanks a lot! @AlexDoanTB , I corrected my license problem according to your advice. I can't find any error message in tb-license.log file now. But I got PSQLException that caused my tb service still failed. I searched thingboard.log file and found the following error message:
"Caused by: org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections."
anyway, I have very appreciated for your grateful help and thanks again.

Hello and a little help here.
I don't have docker running on my AWS, therefore I think my version of Thingsboard PE was installed for Ubuntu Server only.

I do understand all I have to do is to delete this instance-license.data file but I can't find it neither in the folder (/usr/share/thingsboard/bin/) nor by using sudo find ./ -name "instance-license.data in the root folder of the machine

Here is the content of my folder :

Not very clear @Nathan-ma . Is this a clean installation? Were you using ThingsBoard (the license key) somewhere else?

[Nathan-ma]

I fixed it already! But thank you for the quick response! All I had to do was deactivate the license.

The issue has been resolved.

If you are struggling to find /usr/share/thingsboard/bin/instance-license.data, please check, if you are also as stu*id as me an overread your env-variable
TB_LICENSE_INSTANCE_DATA_FILE: /data/license.data
in your docker-compose.yaml. This line of course changes the place of your instance data. So delete it with
rm -f /data/license.data
and then...voila :)

P.S.
I came across multiple Errors like
Terminating application due to critical License Error ACTIVE_INSTANCES_CAPACITY_EXCEEDED(104)
License Error: INVALID_LICENSE_CHECK_SECRET(107) - Invalid secret request sequence number!
and
License Error: INSTANCE_NOT_FOUND(105) - Instance not found!

hope this helps
