Upgrading from Honolulu 1802 to Windows AdminCenter 1804 - site cannot be reached
I have just done the upgrade, it went well, no errors but now the website cannot be reached anymore both from the local server (server 2016) and from other machines.
If I go to the EventLog, I can see a lot of errors like this one :
- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
<Provider Name="SMEGateway" />
<TimeCreated SystemTime="2018-04-13T05:43:09.737478300Z" />
<Data>Signature verificate failed for plugin: C:\Program Files\Windows Admin Center\Esent.Interop.dll</Data>
Signature verificate failed for plugin: C:\Program Files\Windows Admin Center\Microsoft.Diagnostics.Tracing.EventSource.dll

Signature verificate failed for plugin: C:\Program Files\Windows Admin Center\Microsoft.ManagementExperience.FeatureInterface.dll
Signature verificate failed for plugin: C:\Program Files\Windows Admin Center\Microsoft.ManagementExperience.FrontEnd.dll
Do I need to uninstall the Preview first ?

Marc Vanderhaegen, thank you!
As there are no any other solutions yet, we will use that one.
We don't have internet in our enterprise environment on servers.

All worked fine in 1803 build. With upgrade to 1804 can't start service any more because of verification failure.

I uninstalled Honolulu first and then installed WAC on my Win10 machine. I also get the site can't be reached. However, I never got the chance to select the certificate as indicated in the install.
The webpage at https://localhost:6516/ might be temporarily down or it may have moved permanently to a new web address.
Any suggestions on getting this working again? I've tried the DevMode and it doesn't do anything. I've verified the directory is deleted (I've uninstalled/reinstalled twice now) and still get the same error about INADEQUATE TRANSPORT SECURITY.
Thanks Jason, I manage to connect this server to the Internet through our proxy who only allows some specific addresses (Office 365/ Azure), restarted the service, and the problem was solved. In the eventlog there were events that the signature of the files had been verified and now the site is available even when the key DevMode is set to blank.

Nice catch Marc! I can confirm that setting DevMode=1 works on the eval version of Server 2016 Datacenter too; this change creates the listening port after restarting the service.
Microsoft, please either allow the Admin Center to install and run on an air-gapped eval version of Server 2016 with no updates, or release a new eval ISO with the necessary update installed, or at least do not remove the DevMode=1 trick to get it to work.
I found a solution, I don't know if it is the right one but it works.
I went through the registry and found these keys :
Windows Registry Editor Version 5.00
"InstallDir"="C:\\Program Files\\Windows Admin Center\\"
I was intrigued by the value DevMode and changed it to 1, restarted the service and voila :-)
Now the website is up and running.
I did the same procedure on a test server (I was having the same problem on a newly deployed 2016 server) and it solves also the problem.
The problem with the website and the signature messages are related because now in the Eventlog I can see this events : source : SMEGaateway, Event ID 0, Warning, "Unsigned DLL identified: C:\Program Files\Windows Admin Center\Esent.Interop.dll. When run in Production Mode, this will cause the gateway to not run'.
How is it possible to solve the verification problem ? my servers are not able to communicate with the Internet.
In the docs it is said : "Signature verification failed
If you install Windows Admin Center on a machine that has never been online to receive updates, the application may crash with Signature verification failed errors in the event log. After taking updates, the issue will be resolved."
After taking which updates ?
Thanks in advance for your help
If I uninstall the newest version and reinstall the preview 1802 it works again. Any idea ?
