If you're experiencing loading or login issues with Red Sift, it’s often due to network restrictions or blocked URLs. Follow this guide to find out how to resolve them.


Step-by-Step Guide to Fix Red Sift Login Issues

To resolve login errors, ensure that the following URLs are allowed within your network.


Shared Hostnames (All Regions):

  • https://*.redsift-1012.firebaseapp.com

  • https://*.ondmarc.com

UK Region:

  • https://*.redsift.cloud

  • https://*.sync.redsift.cloud

  • https://public.sifts.io

  • https://*.ondmarc.com

EU Region:

  • https://*.eu.redsift.cloud

  • https://*.sync.eu.redsift.cloud

  • https://public.eu.sifts.io

US Region:

  • https://*.us.redsift.cloud

  • https://*.sync.us.redsift.cloud

  • https://public.us.sifts.io

Allowing these URLs ensures that your network does not block the essential connections needed for Red Sift to function properly.


Common Causes of Red Sift Login Errors

  1. Network Restrictions:
    Login errors often occur due to blocked URLs. Ensure the URLs listed above are allowed based on your region.

  2. Firewall Settings:
    Firewalls, VPNs, or security layers like DLP, WAP, or load balancers might restrict the URLs. Check that your firewall settings are not blocking access.

  3. Browser Cache:
    Outdated or corrupted cache files in your browser may lead to login issues. Clear your browser cache or try using an incognito window to resolve this.


Additional Troubleshooting Steps

  • Check Your Internet Connection: Make sure your connection is stable.

  • Update Your Browser: Ensure you're using the latest version of your browser for better compatibility.

  • Network Restrictions: If you’re on a corporate network, consult your IT administrator to confirm that your network isn't restricting access to these URLs.
