bulkssms dont work

Hello
,I have configured bulksms on my server, everything worked ien until a few days ago if you throw me this error

Received close_notify during handshake - SSLProtocolException (... <HttpSmsClient:89 < NotificatorSms:57 < NotificationResource:63 < ...)  

the configuration I have is as follows:

    <entry key='sms.enable'>true</entry>
    <entry key='notificator.types'>web,mail,sms</entry>
    
    <entry key='notificator.sms.manager.class'>org.traccar.sms.HttpSmsClient</entry>
    <entry key='sms.http.url'>https://api.bulksms.com/v1/messages</entry>
    <entry key='sms.http.user'>C90598FFC007412DB5C07C63BB91CE6A-02-4</entry>
    <entry key='sms.http.password'>O0FCR**xOZs5d2xHo#PX!8PeO#ON!</entry>
    <entry key='sms.http.template'>
        {
            "to": "{phone}",
            "body": "{message}"
        }
    </entry>

What's wrong?

Looks like a server issue to me.
