Check This Steps

Step-1 : First you need to check your module is enable or not.

Step-2 : You need to check are you working on right magento url or not.

Step-3 : Check your Route name in routes.xml app\code\VendoreName\ModuleName\etc\frontend

<?xml version="1.0" ?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route frontName="yourroutename" id="yourroutename">
            <module name="VendoreName_ModuleName"/>
        </route>
    </router>
</config>

Step-4 : In above File must be there

Step-5 : Then create contoller (Index) app\code\VendoreName\ModuleName\Controller\Index

Step-6 : Add Action file like this (Index.php) at app\code\VendoreName\ModuleName\Controller\Index (Class Name and File Name must be same)

<?php

namespace VendoreName\ModuleName\Controller\Index;

use Magento\Customer\Model\Session;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\App\RequestInterface;
use Magento\Framework\View\Result\PageFactory;

class Index extends \Magento\Framework\App\Action\Action
{
    protected $resultPageFactory;
    protected $customerSession;

    public function __construct(
        Context $context,
        PageFactory $resultPageFactory,
        Session $customerSession
    ) {
        $this->resultPageFactory = $resultPageFactory;
        $this->customerSession = $customerSession;
        parent::__construct($context);
    }

    public function execute()
    {
        return $this->resultPageFactory->create();
    }
}

Step-7 : Create layout for it in app\code\VendoreName\ModuleName\view\frontend\layout

Step-8 : Layout File name must be like this FrontendRouteName_FrontendControllerName_ActionFileName.xml

Step-9 : Add Blank Page layout like this

<?xml version="1.0"?>

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <referenceContainer name="content">

    </referenceContainer>
</page>

Step-10 : Must be Run Magento Upgrade command before check in fronend.
