webMethods Knowlegebase : javax.net.ssl.SSLException: Received fatal alert: bad_record_mac errors on MWS (1790790)

Problem

Doing runtime MWS deployment, connecting with SSL, on the first stage of deployment’ definition, when choosing our MWS server as the source, and accessing it to choose the MWS assets to deploy, on this stage the MWS server itself getting into SSL errors ,and does not responds correctly to requests.

After 20-40 secs, we will see SSL errors in Browsers as well

In browser (Firefox), it returns:

An error occurred while establishing a secure connection

An error occurred while connecting to {test server address}. SSL received a record with an incorrect message authentication code. Error code: SSL_ERROR_BAD_MAC_READ ...

In Chrome, it returns ERR_CONNECTION_REFUSED.

-> Without "Use SSL" it works properly, no errors raised.

MWS 10.1 Fix3 installed.
