For the problem “failed to load resource: net::err_connection_refused”. I tried to fix it, but it doesn’t work and returns the result I want. Here is my program:
<form [formGroup]="angForm" novalidate>
<div class="message">
<h3> Write to us </h3>
</div>
<div class="form__top">
<div class="form__left">
<div class="form__group">
<input class="form__input form__input--name" type="text" formControlName="name" placeholder="name" #name>
</div>
<div *ngIf="angForm.controls['name'].invalid && (angForm.controls['name'].dirty || angForm.controls['name'].touched)" class="alert alert-danger">
<div *ngIf="angForm.controls['name'].errors.required">
Name is required.
</div>
</div>
<div class="form__group">
<input class="form__input form__input--email" type="email" formControlName="email" placeholder="email" #email>
</div>
<div *ngIf="angForm.controls['email'].invalid && (angForm.controls['message'].dirty || angForm.controls['message'].touched)"
class="alert alert-danger">
<div *ngIf="angForm.controls['message'].errors.required">
message is required.
</div>
</div>
</div>
<div class="form__right">
<div class="form__group">
<textarea class="form__input form__input--textarea" placeholder="Message" formControlName="message" #message
rows="3"></textarea>
</div>
<div *ngIf="angForm.controls['message'].invalid && (angForm.controls['message'].dirty || angForm.controls['message'].touched)"
class="alert alert-danger">
<div *ngIf="angForm.controls['message'].errors.required">
message is required.
</div>
</div>
</div>
</div>
<flash-messages></flash-messages>
<div class="form__down">
<div class="form__group">

Failed to load resource: net::ERR_CONNECTION_REFUSED : :3000/contact/send:1
has occurred. I’ve checked the entire command line but still can’t find the mistake.
The cause:
The reason of this error is that your client application isn’t able to connect with your nodejs servers.
Solution:
Below code can help you resolve your problem effectively. You can refer it:
If nodejs server on port 3000 is running on localhost, it will work.
This error is for anyone else. Verify that NodeJS isn’t crashing. This error can be caused by a previous request that causes the NodeJS server’s to crash or restart.
