Connection errors when using home network

[cattre]

I am unable to create new flows or modify existing ones when on my home network (Talk Talk) using my company laptop. However, I can access Flow (company 0365) without any issues using my personal laptop. The company laptop has got Zscaler installed so that could be the issue.

When I edit an existing flow I get lots of connection errors. All my steps are relabelled "Connections" and simply display "Invalid connection" when I expand them. If I select the "Add new conneciton" option I get something along the following lines:

Failed to create connection for connection id '/providers/Microsoft.PowerApps/apis/shared_office365/connections/shared-office365-71EA1DDB-22AD-40F6-8664-D7F1E175E556'. Failed to fetch

If I try and create a new flow I get an error page with the following:

Time:

Server/Client Correlation ID: 36f593d8-7a25-4d18-a018-731bf2d51fc1

x-ms-client-request-id (Client->Backend Request Header): 08c04453-56fa-43ad-b062-fe86-e9dd2fde

Error: Client request aborted

I also can't get to any of the pages in the "Data" section (e.g. Entities, Connections etc.).

Hi @cattre ,

This seems to be related to the domain you set up on the company laptop.

This seems to involve the Backend service, I am afraid we can't troubleshoot similar problems here, please try to contact support for further assistance:

Just to update this thread in case it helps anyone else, I finally found someone (in my company IT dept) who was aware of this issue. Apparently it is currently logged with Zscaler but the cause is something to do with anti-spoofing employed by some ISPs (in my case TalkTalk but appears to be affecting others as well).

I will provide an update when I hear back but doesn't sound like anyone is taking responsibility to fix currently. Glad to finally have some information though - TalkTalk support had no clue.
