I'm currently working on an app using Google Calendar API.
I'm completely stuck when requesting the Watch content because Google says the URI I've specified for the Channel content is not HTTPS :

URI uri = new URI("https://example.com/optime/googlecalendar/notifications"); Calendar.Events.Watch watched = service.events().watch("primary", new Channel() .setId("ChannelID") .setType("web_hook") .setResourceUri(uri.toURL().toString()) );This URI has been declared in the Google console and is present in the credentials.json file with ID and secrets.
The domain does exist, has a valid, not self-signed certificate :
2025-01-10 10:48:07 app-1 | 2025-01-10 09:48:07,344 DEBUG [jdk.eve.security] (vert.x-internal-blocking-1) X509Certificate: Alg:SHA256withRSA, Serial:473c7bd72d57274b830aaf363f5417fd79c, Subject:CN=example.com, Issuer:CN=R10, O=Let's Encrypt, C=US, Key type:RSA, Length:2048, Cert Id:1053261847, Valid from:1/10/25, 8:48 AM, Valid until:4/10/25, 8:48 AMAn endpoint also exists in a controller :
@Path("/notifications")@POSTpublic Response watch(Object payload) { LOG.debug("WATCH function"); return Response.ok().build();}At this point, I can't understand what I'm missing and I hope someone is able to point the mistake(s) I've made.
Thanx for your time.
