Heroku Postgres requires SSL connections using TLS v1.2 or higher
Change effective on 23 June 2022
Heroku Postgres requires SSL connections using TLS v1.2 or higher.
Heroku is currently running database server upgrades for Heroku Postgres that will make TLS v1.2 the minimum protocol version supported for SSL connections to all databases in Production and Hobby plans.
This requirement was already in place for databases that were created after November 11, 2020 and databases that were already upgraded via maintenances.
