OpenSSL::SSL::SSLError: hostname was not match with the server certificate

OpenSSL::SSL::SSLError: hostname was not match with the server certificate

option 1) disable the ssl and raise all the errors so we can see them in the environment.rb or an initializer somewhere it can't be done in the config

ActionMailer::Base::raise_delivery_errors = true
ActionMailer::Base::smtp_settings[:enable_starttls_auto] = false

option 2) rebuild your snake oil cert ..
before you do this check that its going to work

hostname
openssl x509 -in  /etc/ssl/certs/ssl-cert-snakeoil.pem -noout -text

if the hostnames already match then forget it.. otherwise execute these commands to fix it and check..

make-ssl-cert generate-default-snakeoil --force-overwrite
openssl x509 -in  /etc/ssl/certs/ssl-cert-snakeoil.pem -noout -text
