connecting to AWS documenDB from local using port forwarding set up

Question

Hi All,

I have set up port forwarding using which I am able to connect to studio T3 host details as localhost:27017. But when I try connecting trough prgramatically via springboot application with rds-truststore.jks file I am getting bellow error

Caused by: java.security.cert.CertificateException: No subject alternative names matching IP address localhost found
	at java.base/sun.security.util.HostnameChecker.matchIP(HostnameChecker.java:165) ~[na:na]

	... 23 common frames omitted

it is due to there is no reference of localhost in the rds-truststore.jks file..

How to add the localhost to rds-truststore.jks file ?

Accepted Answer

In my case below string helped in connecting to WS document DB from local machine

mongodb://:@localhost:27017/?tls=true&tlsInsecure=true

Answer

Try these:
* Open the rds-truststore.jks file using keytool utility
* keytool -keystore rds-truststore.jks -storepass  -list
* Add the localhost alias to the truststore
* keytool -keystore rds-truststore.jks -storepass  -alias localhost -import -file localhost.cer
* Provide the path of the updated truststore in the springboot application configuration.
* Restart the springboot application.
* This will add the localhost certificate to the truststore and allow the application to connect to the database using localhost port forwarding without any certificate errors.
