If you're seeing the ERR_SSL_PROTOCOL_ERROR, it's usually due to an issue with your SSL certificate. For most hosting plans, a free SSL certificate is automatically installed on your website, but you can also install it manually if needed.
If your SSL certificate is already installed and you're still getting the error, here are some steps you can try:
Clear your browser cache and history – This can resolve any outdated information causing the issue. You can also try checking the website in incognito or private browsing mode.
Disable your antivirus or firewall temporarily – Sometimes, security software can block SSL connections. Try turning it off and see if the issue persists.
Check your DNS settings – Ensure that your domain is correctly pointing to your website and that the DNS records have fully updated.
Verify your SSL certificate – You can check if your SSL certificate is valid. If it’s not, contact your SSL provider for help. Alternatively you can try uninstalling and reinstall a fresh SSL certificate.
These steps should help you get your website back online securely.
