Hmm... Something went wrong - try again. (Windows Admin Center 1809.5)

Windows Admin Center 1809.5 was working fine earlier today.  Now it is giving this message.

Hmm... Something went wrong - try again.

Windows Admin Center has encountered an error that it cannot recover from. What would you like to do next?

I have tried accessing Windows Admin Center from different computers and different browsers and they all have the same message.  When I click on the "Refresh Windows Admin Center" the page reloads with the same error.  This is installed on a Hyper-V 2016 failover cluster with four nodes.

The lines below are a copy of the browsers console logs.

main.1caa960788810689c09a.bundle.js:1 Welcome to the Windows Admin Center debugging api. Type "MsftSme.help()" to see a list of available commands

Hi Keenan,

I have a similar setup with 2019 Server Cluster and getting the same error.

Did you get this resolved?

@Minh_Huynh I solved this by completely uninstalling Windows Admin Center and re-installing it.
