Dynamic Import Error (retool-edge.com) over Starlink Connection

Hi Retool Support Team,

I am encountering a persistent error when attempting to load a Retool application over a Starlink internet connection.

Error Details:

Troubleshooting Conducted:

  1. Starlink Support: I reached out to Starlink support, and they advised me to contact Retool directly regarding CDN/edge access.

  2. VPN Test: When I connect via Cloudflare WARP/VPN, the application loads immediately without any errors. Disconnecting the VPN causes the dynamic import error to return.

  3. Cache: Hard refreshing and clearing browser cache on the raw connection does not resolve the issue.

It appears there may be an issue with how traffic from Starlink IP ranges / CGNAT gateways is being routed or served by the retool-edge.com CDN. Could you please investigate whether any edge-level blocks, stale cache issues, or IP filtering are affecting Starlink users for this asset domain? Are there other users experiencing the same? Thanks!

Hi @je_end,

Welcome to the Retool forum and thanks for posting!

I had a few asks while I look into this for you.

  • Are you able to try switching your DNS to either 1.1.1.1 or 8.8.8.8. and then try accessing Retool on Starlink.

  • In your terminal of choice, can you run the command nslookup retool-edge.com both on Starlink alone and on your VPN and provide the results here?

  • Can you also run the command curl -I https://retool-edge.com/assets_vjs/main-BXbxQqrF.js on Starlink alone and let me know what the result of that is? (Did the request time out, fail the connection or return a 403?

  • Can you also share your rough location/region? If you're not comfortable sharing that in this thread, feel free to DM me.

Having this additional information will help us narrow down what's going on.

Thank you!
