Failure to use the SMS service of the Traccar SMS Gateway application

Hello everyone, I have my traccar server configured to send push and web notifications, however it asked me to send SMS as well, so I decided to use the traccar SMS gateway app, however the SMS are not sent and a very long ror message appears at the bottom of the screen, this is my configuration

<entry key='notificator.types'>web,firebase,sms</entry>
    <entry key='notificator.firebase.serviceAccount'>
            {
                "type": "service_account",
                "project_id": "PROJECT_ID",
                "private_key_id": "PRIVATE_ID",
                "private_key": "PRIVATE_kEY"
            }
    </entry>


    <entry key='notificator.sms.manager.class'>org.traccar.sms.HttpSmsClient</entry>
    <entry key='sms.http.url'>https://www.traccar.org/sms/</entry>
    <entry key='sms.http.authorization'>TOKEN</entry>
    <entry key='sms.http.template'>
    {
        "to": "{phone}",
        "message": "{message}"
    }
</entry>

I use a similar configuration for a server that had a very old version of traccar, but it works without any problems.

If anyone could help me with this question I would greatly appreciate it. I use Traccar Server version 6.5.

I forgot to mention that web and push notifications work perfectly, the problem is with SMS notifications.

pdta: Sorry for my terrible English

I recommend upgrading first. If it still doesn't work, there's probably some issue with the token.

Hello, greetings, I'm sorry I didn't answer before but I had some serious personal matters, I did the update but all notifications stopped, firebase web and sms (which were already failing), to add context for the frontend, the frontend of a previous version is being used at the request of users, 6.5 to be exact.
My traccar.xml configuration file is exactly the same as I showed it last time, the connection to the database is correct, it seems that the only problem is the notifications, the error it gives is this.

Any help or support on how to resolve this issue will be greatly appreciated.

You cannot use mismatching backend and frontend.

Yes, I suspected it could be that, because the last time I had a similar problem, it was handled like this and it worked. Okay, I'll take my time to download the latest front end from GitHub and run tests. Thanks for the information and your time. As soon as I'm done, I'll update the progress here. Thanks again.

To be clear, I don't know if it's the reason, but it could be.
