Known OpenSSL bug affecting Facebook chat on new CentOS

If you are running a CentOS like us, you probably seen that lately the Facebook Invitations of WordPress Social Invitations failed and a post wall was created instead.

If you check your error logs in dev mode you will see something like:

PHP Warning: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages:
error:100AE081:elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group
error:1408D010:SSL routines:SSL3_GET_KEY_EXCHANGE:EC lib

Digging around with the great support of Knowhost we found that it’s a known bug of the last release and that a lot of people like us is waiting for a fix. Unfortunately we couldn’t find a workaround yet but we will keep you updated.

 UPDATE:

A simple yum update openssl should do the work:

yum update openssl
