I can not send an email via SMTP

Wrote a module for sending emails via gmail to SMTP. Half a year worked fine, there were no problems. That that has ceased to work, returns an error 501

Ошибка: 5.5.4 HELO/EHLO argument ssl://smtp.gmail.com invalid, closing connection. e25sm23107227wmi.21 - gsmtp вместо 250 62 

Tell me, what could happen that stopped all work?

More: A piece of text to send:

 $sendMail = new sendMail("******@gmail.com", "******", 465, "ssl://smtp.gmail.com", "utf-8", "Error Reporting"); $sendMail->From('Error Reporting'); $sendMail->To('******@gmail.com'); $sendMail->Subject('Error Reporting'); $message = 'test test test'; 

send class itself:
