Got a red popup error titled “Error while running \<job name\>” with the popup contents saying:

> Unable to find log in lookup table, this may be caused by attempting to transport call contexts between AppDomains (e.g. with remoting calls)

Jan 4, 2025 7:39 AM: Failed while executing Backup "<job name>" (id: 1)
System.Exception: Unable to find log in lookup table, this may be caused by attempting to transport call contexts between AppDomains (e.g. with remoting calls)
   at Duplicati.Library.Logging.Log.get_CurrentScope()
   at Duplicati.Library.Logging.Log.CloseScope(LogScope scope)
   at Duplicati.Library.Logging.LogScope.Dispose()
   at Duplicati.Server.Runner.Run(IRunnerData data, Boolean fromQueue)

```

Job log completed successfully, but time of error looks like when the run-script-after finished.

The run-script-after does some tests, leaving logs. The last file timestamps were at 7:39:15.

Profiling log shows usual end-of-backup-itself, but not the later error or end of full operation.

> 2025-01-04 07:25:05 -05 - [Profiling-Timer.Finished-Duplicati.Library.Main.Controller-RunBackup]: Running Backup took 0:00:05:02.550

Server log end:

> 2025-01-04 07:25:05 -05 - [Profiling-Timer.Finished-Duplicati.Library.Main.Controller-RunBackup]: Running Backup took 0:00:05:02.550

Status bar and Server state properties look like the backup operation has completed though.

Early morning weirdness on PC wake (or at least first Duplicati use) was a `Connection lost`

> Connection to server was rejected due to invalid authentication.
> 
> Log in again, or re-open the page from the TrayIcon (if applicable)

If it’s relevant, this one (not yet fixed) is at `http://localhost:8200/ngax/index.html#/log/1`

Console which launched Duplicati kept nice and quiet yesterday, but now has this and more:

```plaintext
fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HN9BVKTBTP75", Request id "0HN9BVKTBTP75:0000002F": An unhandled exception was thrown by the application.

         at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.ProcessRequests[TContext](IHttpApplication`1 application)

```

These are in the Application event log, but whatever happened at 7:39 is not (that I could find).

EDIT:

The logout might just be the usual old problem still hanging around. I think I have four tabs, and

[Release: 2.0.9.107 (Canary) 2024-09-11](https://forum.duplicati.com/t/release-2-0-9-107-canary-2024-09-11/18983/75) talks about how Duplicati tends to do this around then.

A tab was `http://localhost:8200/ngax/index.html#/log` which is live log. I copied by Ctrl-A  
Top entry was “Jan 3, 2025 8:17 PM: The operation List has completed”. In server log, it may be

```plaintext
2025-01-03 20:17:04 -05 - [Information-Duplicati.Library.Main.Controller-CompletedOperation]: The operation List has completed
2025-01-04 07:20:02 -05 - [Information-Duplicati.Library.Main.Controller-StartingOperation]: The operation Backup has started

```

where one also sees the scheduled backup starting. The above description says how that ended.  
This TrayIcon started at 8:47:37 AM 1/3/2025. Not sure what else to add. I’ll leave it up for awhile.
