Numeric Pagination on my custom category page - pagination

Question

I have create a custom category page template with numeric pagination but the problem is that i am not able to view 3rd page with posts.
here is my code which i add in Function.php
function custom_pagination($numpages = '', $pagerange = '', $paged='') {
if (empty($pagerange)) {
$pagerange = 2;
}
global $paged;
if (empty($paged)) {
$paged = 1;
}
if ($numpages == '') {
global $wp_query;
$numpages = $wp_query->max_num_pages;
if(!$numpages) {
$numpages = 1;
}
}
$pagination_args = array(
'base' => get_pagenum_link(1) . '%_%',
'format' => '/page/%#%',
'total' => $numpages,
'current' => $paged,
'show_all' => False,
'end_size' => 1,
'mid_size' => $pagerange,
'prev_next' => True,
'prev_text' => __('Previous'),
'next_text' => __('Next'),
'type' => 'plain',
'add_args' => False,
'add_fragment' => ''
);
$paginate_links = paginate_links($pagination_args);
if ($paginate_links) {
echo "<nav class='custom-pagination'>";
echo "<span class='page-numbers page-num'>Page " . $paged . " of " . $numpages . "</span> ";
echo $paginate_links;
echo "</nav>";
}
}

<?php
/**
* Template Name: Custom Page
* The custom page template file
*/
get_header(); ?>
<div class="container">
<?php
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$custom_args = array('post_type' => 'post', 'posts_per_page' => 2, 'paged' => $paged);
$custom_query = new WP_Query( $custom_args ); ?>
<?php if ( $custom_query->have_posts() ) : ?>
<!-- the loop -->
<?php while ( $custom_query->have_posts() ) : $custom_query->the_post(); ?>
<article class="loop">
<h3><?php the_title(); ?></h3>
<div class="content">
<?php the_excerpt(); ?>
</div>
</article>
<?php endwhile; ?>
<!-- end of the loop -->
<!-- pagination here -->
<?php
if (function_exists(custom_pagination)) {
custom_pagination($custom_query->max_num_pages,"",$paged);
}

You need to read Wordpress pagination documentation. Please read below Docs and then recreate your template accordingly
https://codex.wordpress.org/Pagination
https://codex.wordpress.org/Function_Reference/paginate_links
Plugin:
https://wordpress.org/plugins/wp-paginate/
Code Examples;
Functions.php
function pagination($pages = '', $range = 4)
{
$showitems = ($range * 2)+1;
global $paged;
if(empty($paged)) $paged = 1;
if($pages == '')
{
global $wp_query;
$pages = $wp_query->max_num_pages;
if(!$pages)
{
$pages = 1;
}
}
if(1 != $pages)
{
echo "<div class=\"pagination\"><span>Page ".$paged." of ".$pages."</span>";
if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo "<a href='".get_pagenum_link(1)."'>« First</a>";
if($paged > 1 && $showitems < $pages) echo "<a href='".get_pagenum_link($paged - 1)."'>‹ Previous</a>";
for ($i=1; $i <= $pages; $i++)
{
if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems ))
{
echo ($paged == $i)? "<span class=\"current\">".$i."</span>":"".$i."";
}
}
if ($paged < $pages && $showitems < $pages) echo "Next ›";
if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($pages)."'>Last »</a>";
echo "</div>\n";
}
}
Style:
.pagination {
clear:both;
padding:20px 0;
position:relative;
font-size:11px;
line-height:13px;
}
.pagination span, .pagination a {
display:block;
float:left;
margin: 2px 2px 2px 0;
padding:6px 9px 5px 9px;
text-decoration:none;
width:auto;
color:#fff;
background: #555;
}
.pagination a:hover{
color:#fff;
background: #3279BB;
}
.pagination .current{
padding:6px 9px 5px 9px;
background: #3279BB;
color:#fff;
}
And now use following function inside your template, where you need to show pagination
<?php if (function_exists("pagination")) {
pagination($additional_loop->max_num_pages);
} ?>
