sometimes wsdl return "SoapFault exception: [Server] Antech service not available"

[bionimic]

Hi @artisaninweb,

I'm having issue when my soapWrapper tried to get contents from wsdl url like below:

public function initiateSoapWrapper()
    {
        try {
            ini_set('soap.wsdl_cache_enabled',0);
            ini_set('soap.wsdl_cache_ttl',0);
            if (!@file_get_contents($this->getUrl())) {
                $this->soapWrapper = null;
                throw new SoapFault('Server', self::MSG_ANTECH_SERVICE_UNAVAILABLE);
            }

            $this->soapWrapper = (new SoapWrapper())->add(self::NAME, function ($service) {
                $service->wsdl($this->getUrl())
                    ->cache(self::WSDL_CACHE_DISK)
                    ->trace(true)
                    ->options([
                        'login'    => $this->username,
                        'password' => $this->password
                    ]);
            });
        } catch (SoapFault $e) {
            throw $e;
        }
    }

the url is https://dev.antechdiagnostics.com/service/services?wsdl

it always throw this error:
