Hello,
We do not see a reason for “429 too many connections” error from our theme side. We want to propose you few possible solutions which may help, please try them, they should help:
1/ You can change the default WordPress login URL.
2/ Contact your hosting provider and ask if provider’s firewall might block search engines, crawlers, monitoring services, and web apps, causing the 429 too many requests error.
Make contact with your web host’s technical support team and ask them to take a look at your site to fix the error.
Kind Regards,
8theme team
