Any updates on this error?
Also we are now having it after platform upgrade from version 10 to 11.
This is not a problem and something I wouldn't stop any upgrade because of it. I do experience it as well and the support, being helpful, couldn't troubleshoot it easily either.
My belief, is that it is an error that users were having already before, in some specific scenarios in our applications, and, in one of the upgrades of the platform 11 the error started to be successfully making its way into the Service center logs. (maybe it was a bug there error wasn't so noticeable before?)
Having opened a support ticket this was the response:
After checking the logs provided, we could check that the error message in the Production environment is always associated with the following URL:
https://yourdomain/PerformanceProbe/rest/BeaconInternal/WebScreenClientExecutedEvent (Method: POST)
The Performance Probe main purpose is to collect performance metrics using an API called Performance Monitoring API. You can find more information
here.
By looking at the error stack, there is not much information we can retrieve. It indicates the request was cancelled, which could be caused by a variety of reasons, but unfortunately, the stack does not provide us with many clues on what could be the cause. For instance, this
thread suggests that the client closed the request connection before the server could respond.
Taking this into consideration, since this does not have signs of being platform-related, we can only suggest you use Wireshark in order to analyze the traffic and better understand what can be cancelling the requests.

From this response, it seems that I could be anything from application bug to network. if it prevents that post to be made at the beginning of each page request then it gets logged as such.
I suggested that it could be muted somehow just not to fill some logs with errors that, in my view, should be a warning.
Bear in mind, that in my case the error happened in very small numbers, thousands of requests daily but only 5 to 20 errors get logged on a normal day.
Hoped that helped someone.
