Everything is running fine in Prod (hopefully), the problem is in Sandbox.
We have developped a synch between SalesForce and another (ERP) system. Things are running fine untill now.
The cutomer has created a Sandbox in order to test the synch due to a major release of the external system.
He has adapted the Remote Site in Configuration and the new URL - Login & Password in a custom object.
However, we are still receiving an error message : handshake_failure.
Is it possible that this is due to the fact that both top level URL's in Remote Site, in Prod & in Sandbox are the same : https://mail.mycustomer.be:7000 for Prod & https://mail.mycustomer.be:7005 for Sandbox ??
By using another system (VBA), with the given Sandbox URL, login & password : I receive a correct answer from external system => these are corrects.
Anyone any idea ??
