I recently upgraded from SBB 9 to SBB version 14
I am using Delphi XE2
I have a program that uses the HTTPSClient to post to a remote server
Since the upgrade the post is now failing almost immediately with a 100353 error

I changed nothing. I note that there are now three new properties in the HTTPSClient.


I reverted back to the old exe for now in production and it is working stably

Hi Gerald,

The most likely reason for connectivity issues between SBB 9 and SBB 14 is difference in default TLS layer configuration. Following changes in global regulations and best practices in information security, SBB 14 disables old and insecure SSL2 and SSL3 protocol versions, as well as a big share of weak cipher suites. If you connect over HTTPS and not HTTP, your connectivity issue is very likely to have something to do with those changes.

First of all, please try adding SSL3 to the version set (see Versions property) and check if it helps.
