socket hang up error when waiting for response for more then 2.5 minutes

I am running simple test which suppose to discover devise on the network. If discovering process taking more then 2.5 min hitting socket hang up error if less test runs successfully.

describe(`run discovery from scratch TG(model: XGH1) ${ip}`, () => {
it('clean db', async () => {
await runShellScript(no, pa, db);
});
it('should return true if device discovered successfully', async () => {
const dresult = await request.put(`/resources/discover/${ip}/${db}`);
dresult.ok.should.be.true;
});
});

Received error:
1) run discovery from scratch TG(model: XGH1):
should return true if device discovered successfully:
