Spring App on GCP - Cloud Run - HTTPS only - This combination of host and port requires TLS

My Spring app uses lets encrypt and is https only. I did not include http to https thing, as it worked for me in postman with https:// format

When I deployed to Cloud Run, and mentioned the custom port (the port specified in spring) and tested using URL from dashboard

https://..blah..run.app

I am getting error/message

Bad Request This combination of host and port requires TLS.

What configuration is required on Cloud Run to resolve this?

The url as I see on service details page has htpps://... enter image description here

EDIT: If Cloudrun does not need me to take case of SSL, I can remove the application properties entries

server.ssl.key-store-type=PKCS12
server.ssl.key-store=classpath:key/keystore.p12
server.ssl.key-store-password=${lets.secret}
server.ssl.key-alias=someCertAlias
server.ssl.enabled=true

So Can I get an answer on whether to remove SSL from spring? If cloudrun always uses http, all my calls use redirectConnector, which seems pointless

The Cloud Run Service listens on HTTP and HTTPS. Your application running in the container must listen on a port configured with HTTP only.

FYI: For a public facing web server, you should almost always enable HTTP. Otherwise, when a user enters www.example.com in the browser, the user will receive a connect error. This not always the case, for example .dev gTLDs, but is good practice. When a user connects to Cloud Run with the HTTP protocol, Cloud Run will redirect the user to HTTPS and connect to your application using the HTTP protocol.
