Scrapy: Going Past Page 4 of eBay?

for some reason Scrapy stops rendering pages after page 4, why is this?

My code:

import scrapy
from scrapy_splash import SplashRequest
import csv

class Description(scrapy.Spider):
    name = 'Description'
    auction_URL = ''

    def start_requests(self):
        yield SplashRequest(url=self.auction_URL, callback=self.parse,
                            args={'wait': 3},

    def parse(self, response):
        items = []
        for product in response.css('li.s-item'):
            title = product.css('h3.s-item__title.s-item__title--has-tags::text').get()
            subtitle = product.css('div.s-item__subtitle::text').get()
            productURL = product.css('a.s-item__link::attr(href)').get()
            for x in product.css('div.s-item__details.clearfix'):
                price = x.css('span.POSITIVE::text').get()

                item = {
                    "title": title,
                    "subtitle": subtitle,
                    "price": price,
                    "url": productURL
        keys = items[0].keys()
        with open(r'C:\Users\Hugo\Documents\CSV export\info.csv', 'a', newline='') as output_file:
            dict_writer = csv.DictWriter(output_file, keys)

As you can see, it works on the page currently in place. However if you change it to:


It no longer finds anything, been trying to work out why this is for a while now haha1.
