GetEventLines fail on a installation (2026 R1)

Hi,

One user that using my Colored Timeline Pluing experience a strange, error that events are not loaded, I am unable to reproduce, wireshark trace just show that conn get RST, so ES close it.

this is the GH issue: How to get Colored Timeline admin plugin working - GetEventLines / AlarmServiceToken failure on XProtect 2026 R1 · Cacsjep/mscp · Discussion #190 · GitHub

this is the MIP Exception Error: An error occurred while receiving the HTTP response to http://xxx:22331/Central/AlarmServiceToken. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down)

User means with SC on same machine he get alerts.

ES logs also in GH issue trace.

basically i am out of ideas, because i just invoke the MIP Call.

          {
              Conditions = new[]
              {
                  new Condition { Target = Target.Timestamp, Operator = Operator.GreaterThan, Value = DateTime.UtcNow.AddHours(-24) },
                  new Condition { Target = Target.Timestamp, Operator = Operator.LessThan,    Value = DateTime.UtcNow.AddMinutes(1) }
              },
              Orders = new[] { new OrderBy { Target = Target.Timestamp, Order = Order.Descending } }
          };
          
          if (ct.IsCancellationRequested) return;
          var rows = alarmClient.GetEventLines(0, int.MaxValue, filter) ?? Array.Empty<EventLine>();
          if (ct.IsCancellationRequested) return;
          
          // Optional client-side filter for "Show only events from selected cameras".
          // EventFilter Conditions are AND-combined, so multiple cameras can't be expressed
          // server-side without N round-trips - the dataset is already capped at 24 h, so
          // post-filtering is fine.
          HashSet<Guid> selectedSet = onlySelected ? new HashSet<Guid>(selectedSnapshot) : null;
          
          // No dedup - one row per EventLog entry. Cap at MaxRows newest-first so the
          // grid stays responsive on busy systems.

This issue entry has the complete expection with inner expection:

So for any reason ES decide to close and not to answer.

Just so I understand the situation correctly:

Does the plugin work as expected at other customer sites, and only this specific installation is experiencing the issue?
Is this the first time the plugin has been tested against XProtect 2026 R1, or is it already known to work in your test environment on that version?
I do not know whether it is related, but could you also confirm the encryption configuration of the installation? Is encryption enabled or disabled in the Server Configurator?

The answers may help determine whether this is a version-specific issue or something unique to the environment.

I’ll chime in on most of these, as I’m the user trying to get it to work -

I have myself been able to install it on XProtect Express+ 2026 R1 in a test environment (non-encrypted) and I did not get that error.
I can confirm the encryption is disabled on the system where I’m getting that error.

Question 1 @ChristophAcs can answer

Our test environment is a standalone server, and is very different compared to our production environment where there is a separation of duties across 3 servers

no reported issue on other users, systems.

I suspect a bug and I have opened a bug report with Milestone Development. I will let you know what they find.
