IIS not starting dashboard

PowerShell Universal Universal Dashboard

Is me again :slight_smile:

I just upgraded my live PSU server (IIS hosted) from 1.5.12 to latest and now it seems dashboards will not start. Log will show the below stack trace. Admin page loads with no issues, is just when I click start for the one dashboard I have. I can provide the full log file if needed.

Can you look in the dashboard log within the admin console? This log looks like it’s failing to start the dashboard but the log in the console might have a better error message.

3

For some reason the log console will not display anything (web). If it does log, where could I find the file? Maybe this way I can provide the error if any.

4

When you upgraded, did you use Unblock-File against the files? The could prevent it from starting. It should be logging to that log in the web. That’s the only place it writes that log.

5

I did that but let me redo just to make sure.

6

Oh man!! It was very silly the issue. Had to change PowerShell environments back and forth (7.1 → 5.0 → 7.1)

7

Oh, that’s pretty weird. I’ll open a bug for this and see if I can track down what happened. I haven’t noticed this before but it will be good to see if I can figure it out. Would hate to have this happen each time.

8

For sure.

Very weird indeed. But thank you for the assist :slight_smile:
