It would seem that a firewall or proxy is blocking your access to the Tabular Editor online service endpoint. Please have your IT department unblock the domain api.tabulareditor.com for outbound https (port 443) access.

I am at home on my personal PC, and I don't have any firewall or proxy configured. If I check the URL you provided with Postman or Edge, I get a correct response. I have been experiencing this issue since at least v3.15

Unfortunately we're not able to reproduce this on our side. Could you try changing the proxy settings inside the app from System to None or vice versa (depending on the current setting), then restart the app and try again?

If this still doesn't work, it would be useful if you could try to set up a Fiddler trace, so we can see if there are any differences between you accessing the endpoint in Postman vs. Tabular Editor.

I tried changing the proxy setting from None to System (and back again, restarting the app between changes), but the problem persisted. I will try to setup a Fiddler trace and come back with my findings.

I tried running the Fiddler trace as suggested, and even though I was able to see the requests from Postman, I was unable to see any activity from TE3. Below is a screenshot from the trace, I clicked several times the Check for updates button but nothing showed up in Fiddler.

I also tried turning off Windows Firewall but the problem persisted.

Is there a way of generating logs to see exactly the request and response that are being generated?

This is weird. Are you using the .NET 6 or .NET 8 build? Regardless of which one you tried, could you try the other as well? (Portable version should be fine).

Also, it should be possible to capture more detailed logs using Windows Event Viewer:

• Open Event Viewer.
• Navigate to Applications and Services Logs → Microsoft → Windows → HttpClient → Operational.
• Right-click Operational and select Enable Log.

Once this is enabled, try to launch TE3 again and attempt to check for updates a few times. Then, kindly report back here with any events generated.

I have installed the .NET 8 build. Tried also with the .NET 6 portable build, same results.

I tried enabling the log you suggested, but I cannot find it. I tried enabling the other Http logs I found but I was unable to generate any events on them by trying to search for updates in TE3.
