I am trying to set up a GCP Load Balancer for my Cloud Run instances. As I've understood, I have to define a Backend, a Routing Rule and an A-Record for each of my cloud run. I would like to redirect all unmatched to my website, so I switched to the "Advanced host and path rule", in the Default one I set "Redirect the client to different host/path", add my full domain (https://example.com) in the "Host redirect" field and enabled HTTPS.
When navigating to the IP of my balancer "https://<balancer_ip>" I expected to be redirected to my home page, but I get ERR_SSL_VERSION_OR_CIPHER_MISMATCH.
Am I right? I am missing something?
It ended up, that the IT did not set up correctly the DNS. Once fixed the A-Record(s), it worked.
