Change Node express Timeout try connection - node.js

Question

i'm trying to change the timeout of a post express method using node-expose-sspi for authentication.
The problem is, none of what i tried worked so far.
My goal is to set the connection timeout 5s instead of the standard 120s.
When i enter the right credentials the code take approximately between 0.3s and 1.5s, and when the credentials are wrong the code takes between 7s to 120s
The "actual" code is:
const app = express();
app.post('myRoute', async (req, res) => {
try {
const domain = sso.getDefaultDomain();
const credentials: UserCredential = {
domain,
user: req.body.login,
password: req.body.password,
};
const ssoObject = await sso.connect(credentials);
if (ssoObject) {
req.session.sso = ssoObject;
return res.json({
sso: req.session.sso,
});
}
} catch (err) {
return res.status(401).json({
error: 'bad login/password.',
});
}
});
What i've tried so far was:
Change globally setTimeout:
var server = app.listen();
server.setTimeout(5000);
Change res inside the method:
res.setTimeout(5000, () => {
console.log('Request has timed out.');
res.send(408);
});
And Promise race:
let promisseConnect = new Promise(async (resolve, reject) => {
try {
const domain = sso.getDefaultDomain();
const credentials: UserCredential = {
domain,
user: req.body.login,
password: req.body.password,
};
const ssoObject = await sso.connect(credentials);
if(ssoObject){
resolve(ssoObject);
}else{
reject(401);
}
} catch (error) {
reject(401);
}
})
let promisseTimer = new Promise((resolve, reject) => {
let wait = setTimeout(() => {
clearTimeout(wait);
resolve(408)
}, 1000)
})
Promise.race([
promisseConnect,
promisseTimer,
])
.then((res) => console.log(res))
.catch((res) => console.log(res))
All of then didn't showed any error messages as far i remember, just the usual message after tried connection for 120s.
