Angular tests fails with ng e2e but pass with protractor conf.js

Question

while working on test automation for angular apps, i faced a problem that whenever I try to run the test suit with angular command ng e2e all the tests fail. The same tests get passed with protractor command protractor conf.js. I want to ask the reason for this weird behavior. The spec is provided. Thanks

import { AddMemberClass } from '../../pages/add-member/add-member.page';
import { LoginPage } from '../../pages/login/login.page';
import { browser, promise, by } from 'protractor';


fdescribe('Add Member as Admin',()=>{

    let addMemeber: AddMemberClass;
    let login : LoginPage;

    beforeAll(()=>{
        login = new LoginPage();
        addMemeber = new AddMemberClass();
        return new Promise((resolve)=>{
            login.navigateTo().then(()=>{
                login.getEmailInput().sendKeys('[email protected]');
                login.getPasswordInput().sendKeys('13235');
                login.getLoginButton().click().then(()=>{
                    setTimeout(()=>{
                        expect(browser.getCurrentUrl()).toContain('organization').then(()=>{
                            resolve();
                            });
                    },30000);
                });
            });
        });    
    }); 
    
    it('should login successfully', ()=>{
        return addMemeber.getMemberMenu().click().then(()=>{
            console.log('test1');
            return addMemeber.getAddMemberSubMenu().click().then(()=>{
                 console.log('inside test 1');
                return  new Promise((resolve)=>{
                    setTimeout(()=>{
                        expect(browser.getCurrentUrl()).toContain('directregistration').then(()=>{
                        resolve();
                        });
                    },30000)
                })
            })
        })
        
    });    
   
    it('should check member Menu on main page',()=>{
        return new Promise((resolve,reject)=>{
           setTimeout(()=>{
                console.log('Inside test 2 timeout');
                expect(addMemeber.getMemberMenu().isPresent()).toBe(true);
                resolve();
            },5000)    
        });     
    });

  
    })

});

The issue I was facing is with ng e2e it first serves the app and then run e2e test cases. With running the command protractor conf.js, it was not served, creating issue and failing all test cases
