Troubleshoot OpenSSL 3.0 Connections


As of SingleStoreDB Cloud 8.1, OpenSSL 3.0 is now used to establish secure connections to SingleStoreDB Cloud. As a consequence, a client certificate that uses SHA or MD5 hash functions in its signature must be replaced with a certificate that uses SHA256 at a minimum, or a secure connection to SingleStoreDB Cloud cannot be established.

Connect After Upgrading

As this file is always kept up to date, you may download the singlestore_bundle.pem certificate and use it to connect to SingleStoreDB Cloud 8.1.


The singlestore_bundle.pem file, which SQL clients can use to connect to SingleStoreDB Cloud, will be updated as of October 20, 2023.

If your SQL client uses the singlestore_bundle.pem file and the --ssl-mode=VERIFY_CA flag to connect, and your SQL client can no longer connect to SingleStoreDB Cloud, please download and use the latest singlestore_bundle.pem file.
