The SSL connection to the remote server could not be established

[luke_duncan]

Using ActiveMerchant Ruby gem for all of our Authorize.net needs. We have had the same code working for several years, and all of our SSL certificates are up to date.

Has there been any change on Authorize.net's side that we would receive this error:

ActiveMerchant::ConnectionError: The SSL connection to the remote server could not be established

It is only happening for Authorize.net and we can't seem to figure out why this would be happening? We allow for our users to input their authorize.net api keys, and this person who is receiving the errors has been our customer for several years and they double checked everything as well. 

Any help on this would be great!

I was having the same issue. Our web server code hadn't changed, but suddently we couldn't connect to authorize.net.

I was running activemerchant 1.47.0. When I updated that to 1.78.0 everything worked fine again.

Update activemerchant and this should resolve for you. Thanks!
