Hi Bijan,
>> Bruce, do we need to start using their certificates?
no, their certificate change will have no impact on your or your program.
However I suspect they took the opportunity to change some other things as well....
>> We are getting error -53. This just started happening today.
I suspect you are connecting with an SSL Method they no longer support.
a) make sure you are on the 8.51 build
b) the default SSLMethod is now TLS (ie TLS1.0, 1.1 or 1.2) so unless you are overriding the default it will likely just work.
If you are overriding the default SSLMethod then I guess you need to change the setting.
cheers
Bruce
