Hi @Cj-S1dTy

I could not reproduce the errors you mentioned above on the latest version of Test-Harness (TH).
Thanks for sharing the PICS files you used, but we lack more information.
Could you please provide more files like the test and DUT logs, the TH versions you used, the configuration from the TH's UI, etc.

Hi @antonio-amjr ，Attached is the latest test log documenting the same problem in the ACL

Hi @Cj-S1dTy

Taking a look in the logs and the example in the description, I believe the real issue here is the error keepalive ping timeout; no close frame received that happens executing TC-ACL-2.6 and triggers the "connecting to ws..." error for all following tests executed after.

For the record, this behavior was mentioned before in the comment #273 (comment) where a "Keepalive ping timeout" error also happened and triggering subsequent errors for others tests as well.

This problem is being tracked by issue#29194 of the SDK team (connectedhomeip repo) but I'm not aware of any news on that matter.

In my case I'm not able to reproduce this issue so I'm wondering if anything else is different in our environment.
So a couple of question for you would be:

• What's the ubuntu version?
• Is a real DUT being used? (please provide the logs from the DUT, maybe could help)
• Is the v2.11+fall2024 updated? The SHA being used is not the latest
