2FA failed on live server

[phantomAA92]

on local, it works well but on live server, it always failed.

const randomBuffer = crypto.randomBytes(10); // 80 bits
const encoder = new base32.Encoder();
const secret = encoder.write(randomBuffer).finalize();

const { verificationCode, totpSecret } = req.body;
const decodedSecret = new base32.Decoder().write(totpSecret).finalize();
const verified = notp.totp.verify(verificationCode, decodedSecret, { window: 1 });

Can you help me???
