The certificate for this server is invalid. You might be connecting to a server that is pretending to be “...” which could put your confidential information at risk.

I am trying to do this but get error (IOS 14.2):

The certificate for this server is invalid. You might be connecting to a server that is pretending to be “https://…” which could put your confidential information at risk.

I copied the .cer certificate into xcode and do this:

const response = await fetch(url, {
        method: 'POST',
        body: body,
        pkPinning: true,
        disableAllSecurity: false,
        // your certificates array (needed only in android) ios will pick it automatically
        sslPinning: {
          certs: ['my_cer_file_without_extension'], // your certificates name (without extension)
        },
        headers: {
          Accept: 'application/json; charset=utf-8',
          'Access-Control-Allow-Origin': '*',
          e_platform: 'mobile',
        },
      });

Am I doing something wrong or is it no longer working? Any ideas?

The certificate generated by using the key chain of Mac can solve this problem

@in-html If you resolved this issue, can you share the solution? Working well on android, but not on iOS.
