SSL Pinning failed: Certificate is not trusted or store is empty.

[PixelsTv]

I have two servers one where I store the fingerprints.json (Server1) and the other where api (Server 2) calls are made from my swift app, when I create the fingerprints for the Server 1 the swift app runs as expected and the SLL Pinning works perfect but when I do the exact same steps for my Server 2, I get "SSL Pinning failed: Certificate is not trusted or store is empty.", I've checked the fingerprint many times and for some reason no matter how many times I generate both. Server 1 always works but Server 2 is always showing that error. Please help
`let validationResult = certStore.validate(challenge: challenge)

    switch validationResult {
    case .trusted:
        completionHandler(.performDefaultHandling, nil)
    case .untrusted, .empty:
        completionHandler(.cancelAuthenticationChallenge, nil)
        print("SSL Pinning failed: Certificate is not trusted or store is empty.")
    }`
