Spring Boot Images not served over HTTPS

I have a weird error.

I have some images lying in a folder on my server in /media/uploads

I then served these images over a Spring Boot application with this Controller:

@GetMapping("/image/{name}")    fun getImage(@PathVariable name: String): ResponseEntity<Resource> {        val path = Paths.get("$PATH/$name")        val resource = UrlResource(path.toUri())        return ResponseEntity.ok().contentType(MediaType.IMAGE_JPEG).body(resource)    }

When using this over http I have no problems at all, but as soon as I enable SSL this endpoint stops working, which means the /image endpoint is not reachable at all over https. All other sites seem to work except they don't load these images.

My application.properties if this helps:

server.port=443server.ssl.key-store=/root/foto/certificate.pfxserver.ssl.key-store-password=***server.ssl.keyStoreType=PKCS12

I already tried:

• still serving the images over http (but http requests inside https sites get blocked)
• serving both http and https

Any ideas would be appreciated
