Azure SQL Database error TLS Handshake failed since v12 upgrade

Question

I receive this error since this morning, new v12 updated server / Azure SQL Database:

TLS Handshake failed: x509: certificate is valid for tr12.nort

Answer 1

Based on this closed issue I changed TrustServerCertificate from False to True and added this parameter hostNameInCertificate to the connection string and it is working now:

https://github.com/denisenkom/go-mssqldb/issues/55

TrustServerCertificate=True;hostNameInCertificate=*.database.windows.net;

Azure portal suggests to have TrustServerCertificate=False and no hostNameInCertificate.
