Problem Description:

Encountered the following error when attempting to access the web GUI of a Sonus SBC 1000/2000 using https://<IP_Addr>:

GOOGLE CHROME

This site can't provide a secure connection

10.22.203.15 uses an unsupported protocol.

MOZILLA FIREFOX

An error occurred during a connection to 10.22.203.15. Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

INTERNET EXPLORER

Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://10.22.203.15 again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.

 

RESOLUTION:

  1. In INTERNET EXPLORER, go to Tools, Options, select Advanced Tab, scroll down to Security section and check box next to SSL2.0, SSL3.0, and TLS1.0 and uncheck TLS1.1 and TLS1.2.
  2. Upgrade SBC firmware from 4.1.1 to 7.0.2. After upgrading, should be able to access with any browser.
