Automation Studio 6 Upgrade Dialog has no Internet Access

[Niklas_Richter]

Does anybody else have the issue with Automation Studio 6 that the Upgrade Dialog has no Access to the internet?
Or does anybody know how to fix this.

The upgrade dialog service is running and i tried starting the automation studio as an admin.

Hi Niklas,

Unfortunately, I run into the same problem quite often, especially in AS6, even with the latest version 6.5.
You can try the suggestions provided here:

The Upgrade service accesses our homepage to download the upgrade files and allowing this the problem was sol…

What often helps me is restarting the service and clearing the C:\Temp folder.

Hi Niklas, this is a known issue with the B&R AS Upgrades Service in AS 6.5.2. It has been addressed in AS 6.5.3 (scheduled to be released later this week) and AS 6.7.0 (scheduled to be released 1 June 2026).

@Niklas_Richter please update us if new version of AS really fix your issue. Thanks.

Hi Niklas,

Here’s what else I’ve found out: If the upgrade service shows that it has no internet connection again, I restart the service. It’s important to wait a while until the service has restarted. You don’t get any feedback, but I always have to wait about 2 minutes. If I don’t wait that long, I get the same message (no internet) again.

There is since today also a new AS version available where some issues with Tools-Upgrades were solved:

@kovarj

I installed the new AS 6.5.3.11 and the “no internet access”-issue seems to be solved.

However, now I get the following error after downloading a upgrade:
“The underlying connection has been closed: A trust relationship could not be established for the secure SSL/TLS channel.”

Do you know if the “solved problem” in the revision information for the 6.5.3 (which @jan.van-de-wielle posted ) should adress this problem?

I found one or two community post dealing with the same issue. But as far as i understand this was only a problem for Automation Studio < V4.6.
Since I am using the newest version this should not be the issue. Does anybody know how to fix this?

Hi Niklas, it looks like someone else created a new topic for the “underlying connection has been closed” issue: B&R Upgrades SSL/TLS failed . I would recommend we continue troubleshooting that issue there. Would you mind marking one of the previous replies as a resolution so we can consider this specific issue closed? Thank you.
