cURL error 7 failed to connect to port 443

  • Hello,

    I have done no changes to my website in past months, but all of sudden this monday my web has stopped working. It has slowed down a lot and was unable to update both WP and plugins. I have cleared FTP and performed clean WP intalation, however the problem still occurs.

    The error I was getting was:
    curl error 7: failed connect to downloads.www.remarpro.com:443; connection timed out

    Now I am getting:
    cURL error 7: Failed connect to lvvodotopo.cz:443; Connection timed out (http_request_failed)

    I found some solutions on google, but these problem occur mostly on localhost websites. It seems to be some problem with firewall – maybe WP is blocking me?

  • Your WordPress site is having trouble connecting to external resources, likely due to network or server issues. Let’s troubleshoot this step by step:

    1. Check Your Hosting Provider Status: Sometimes, server issues or outages from your hosting provider can cause these types of problems. Check if your hosting provider has any ongoing network issues or maintenance.
    2. Firewall and Security Plugins: Firewall or security plugins on your WordPress site could block outgoing connections. Check if you have any security plugins enabled and if they have any settings that might block external connections. Temporarily disable them to test if they are causing the issue.
    3. Server Firewall: Your server’s firewall may be blocking outgoing connections. If you have access to your server, check its firewall settings to ensure it’s not blocking outbound requests to downloads.www.remarpro.com or other necessary resources. You might need to contact your hosting provider for assistance with this.
    4. Check DNS Settings: Ensure that your server’s DNS settings are correctly configured. If your server can’t resolve DNS properly, it won’t be able to connect to external resources. You can try changing your DNS servers to use a reliable service like Google’s (8.8.8.8 and 8.8.4.4) to see if that resolves the issue.
    5. Proxy or VPN: If you are using a proxy or VPN, it might be causing the connection issue. Disable any proxy or VPN settings and try accessing your website again.
    6. Check Server Resources: If your server is running out of resources, it might struggle to make outgoing connections. Check your server’s CPU and memory usage to ensure it’s not overloaded.
    7. Contact Hosting Support: If you can’t identify the issue after trying the above steps, it’s a good idea to contact your hosting provider’s support. They should be able to investigate server-level issues and help you resolve them.
    8. Check Domain and SSL: Ensure that your domain’s DNS settings are correct, and your SSL certificate is valid and properly configured. SSL errors can sometimes cause connection issues.
    9. WordPress Core and Plugins: Ensure that your WordPress core files and plugins are up to date and compatible with your WordPress version.
    10. Testing on a Different Network: Try accessing your website from a different network or computer to rule out local network issues.
