My sitemap contains 50,000 URLs / 7.8 MB and the following URL syntax:
https://www.ninjogos.com.br/resultados?pesquisa=vestido, maquiagem, 2019-10-03T17:12:01-03:00 1.00
The problems are:
• The search console indicates that "The site map could not be read".
• Loading the Sitemap takes 1 hour and Chrome stops working.
• In Firefox, the Sitemap downloaded in 1483ms and fully loaded after 5 minutes);
Things I did without success:
• disable GZip compression;
• Delete my .htaccess file;
• Create a Test Sitemap with 1 KB URLs and the same syntax that you sent to the Search Console. It worked, but the Sitemap of 50,000 URLs still indicates "" the inability to retrieve the Sitemap ";
• I tried to inspect the URL directly, but this gave an error and asked to try again later while the 1K URL was working;
• I tried to validate the Sitemap on five different sites (YANDEX, ETC) and all worked without error or warning.
