Retool Status

Identified: Comcast Business SecurityEdge customers may find that the workaround mentioned does not work, and neither does allowlisting the retool-edge.com domain. In these cases, disabling SecurityEdge has been successful.

If you are still experiencing issues after trying the DNS workaround, we recommend reaching out to your IT team to check whether retool-edge.com has been added to a block list at the device profile or network level. Some filtering policies may be blocking the domain regardless of your DNS settings.

We are continuing to work with ISPs to unblock the domain and will provide updates as we have them.

Identified: While we work on removing the ISP blocks, here is a workaround.

You can temporarily resolve this by switching to a trusted public DNS resolver such as 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).

Mac:

1. System Settings → Network → select your connection → Details
2. Click the DNS tab
3. Add 1.1.1.1 or another trusted DNS resolver
4. Click OK

Windows 11:

1. Settings → Network & Internet → select your connection (WiFi or Ethernet)
2. Scroll down to DNS server assignment → click Edit
3. Change to Manual, toggle on IPv4, enter 1.1.1.1 or another trusted DNS resolver
4. Click Save

If you are not familiar with making these changes or your devices are managed by your organization, please reach out to your IT or infrastructure team for assistance.

We are actively working to resolve the underlying issue. We will provide updates as we have them.

Identified: We've identified the issue is due to certain ISPs blocking the retool-edge.com domain. Confirmed ISPs are Comcast Business and Optimum (Altice USA / Cabelvision).
