Hi guys,  
  
After running a successful campaign of 5000 leads, I had to run 2 other campaigns with 100 and 3000 leads.  
  
But I am getting the following error message and the mail are not sent:  
  
  
  
PHP Warning: fwrite(): SSL operation failed with code 1. OpenSSL Error messages:  
  
error:1409F07F:SSL routines:SSL3\_WRITE\_PENDING:bad write retry in /var/www/mautic/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php on line 232  
  
  
  
Any idea where it can come from?  
  
  
  
Thank you

For info, the connection with my SSH server and my crappy connection at home cut.  
It might cause the SSL\_WRITE\_PENDING…  
I had to unpublish the campaign having the issue to run the other one.

But I will have to finish the campaign having this isssue anyway…
