Soapcliente() PHP query with HTTP URL being consulted via domain with HTTPS SSL - Error 500

Question

I have an internal project in the company, where I perform a query in a SOAP webservice whose URL is at http.

I am with a Linux VPS Ubuntu 18 where in the domain linked to the ip of this VPS, a ssl certificate was applied via "certbot".

When trying to perform the query for a PHP script, error 500 is returned.

When I comment on the part of the code responsible for the consultation via SoapClient(), the code is executed normally.

Is there any configuration that should be applied in this structure to avoid this incompatibility.

Sorry if you are asking something very simple, because I am a beginner and I have many questions.

Grateful for any help.

//////////////////////////////////// Consulta no Webservice
$soapcliente = new SoapClient('http://wsgsxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?WSDL');
$param = array (
            'EmpCliente' => $EmpClient,
            'Login' => $Login,
            'Senha' => $Senha,
            'ObterLocalizacao' => 'false'
);

$response = $soapcliente -> Lista_UltimasPosicoes($param);
$array = json_decode(json_encode($response), true);

$retorno = $array['Lista_UltimasPosicoesResult']['Posicao'];
$count_retorno = count($retorno);
