Hello. This document has the ports which need to be opened. Configure your Firewall | Community It doesn't reference Fabric Lakehouse.. are you able to advise what we need to open for the ingest service to communicate to Fabric Lakehouse?

Thanks

Hi,

it depends on your Fabric setup: if you are using private link at the tenant or workspace level, traffic inbound to Fabric may be closed off if your Ingest service lives in a network that cannot reach those private links.

Otherwise traffic to fabric runs over *.fabric.microsoft.com on port 443 using TCP

HI ​@Christian Hauggaard , we are currently getting an error when trying to create the lakehouse storage from within the TDI app, and are getting and authentication failed error. So, I assume it is an issue with permissions rather than the firewall. (I have a ticket open on this # 41178)

Thanks
