Hi all. I'm trying to use ktor with jwt and I'm getting the following error:

My config.

fun Application.configureSecurity() {
  authentication {
      val issuer = "issuer"
      val jwkProvider = JwkProviderBuilder(issuer)
        .cached(10, 24, TimeUnit.HOURS)
        .rateLimited(10, 1, TimeUnit.MINUTES)
        .build()
      val jwtAudience = "audience"
      realm = "realm"
      verifier(jwkProvider, issuer) {
        acceptLeeway(3)
      }
      validate { credential ->
        if (credential.payload.audience.contains(jwtAudience)) JWTPrincipal(credential.payload) else null
      }
    }
}

fun generateJwt(user: User, roles: List<Role>): Result<String> = runCatching {
  val publicKey = readPublicKey("path to public key")
  val privateKey = readPrivateKey("path to private key",  "password")
  JWT.create()
    .withAudience("audience")
    .withIssuer("issuer")
    .withExpiresAt(Date(System.currentTimeMillis() + 7200000))
    .withClaim("username", user.username)
    .withClaim("email", user.email)
    .withClaim("company", user.company)
    .withArrayClaim("roles", roles.map { it.type.value }.toTypedArray())
    .sign(Algorithm.RSA512(publicKey, privateKey))
}.onFailure {
  Log.debug()
  throw it
}

authenticate {
  get("/test") {
   // return OK
 }
}

Seems like no jwks provided

com.auth0.jwk.NetworkException: Cannot obtain jwks from url <https://localhost:8080/.well-known/jwks.json>

this had never happened before. How to fix?
