+# Force SSL When Making A psql Connection
+
+If you try connecting `psql` to a Postgres server that requires SSL
+connections, you'll see an error message like this:
+
+```
+psql: error: FATAL:  SSL/TLS required
+```
+
+You can tell `psql` to make an SSL connection by adding the `sslmode=require`
+key-value pair to the connection.
+
+If you're using a connection string, that might look like this:
+
+```bash
+$ psql postgres://username:password@host.com/dbname?sslmode=require
+```
+
+Or if you're using the connection parameter flags, it may look like this, using
+the `--set` flag:
+
+```bash
+$ PGPASSWORD=password psql \
+    --set=sslmode=require \
+    -h host.com \
+    -U username \
+    dbname
+```
+
+If after adding `sslmode=require`, you find that SSL support is not compiled
+in, [follow the instructions in this post to reinstall Postgres with SSL
+support](https://dev.to/jbranchaud/reinstall-postgresql-with-openssl-using-asdf-cmj).
