Issue/Introduction
SSH failure when BusinessConnect tries to connect with a trading partner.
Resolution
This issue is caused by BC not supporting the cipher that the trading partner server prefers. To work around the issue, go to the trading partner's protocol SSH transport screen (outbound) or BusinessAgreement transport SSH screen, and set the "Preferred Cipher" to "Any".
