upgrade to 2022.3.0 - with Web Error HTTP Error 500.30 - ASP.NET Core app failed to start

Hello,

Just to confirm, were you trying to upgrade to the initial beta (2022.3.0), or the latest version (2022.3.3), which was released earlier today? https://devolutions.net/server/release-notes

Could you go to the Event Viewer on the server hosting the Devolutions Server, expand the Windows Logs folder, and select the Application event log. In it, there will be more details on the 500.30 error.

You can can take a screenshot of the 2-3 errors and either post them here, or send them to service@devolutions.net

Best regards,

sorry subject line was misleading. Upgrade to 2022.3.3 (released today). I will send over the app log, I am not seeing any of the 500 errors in there.

Hi

I had the same error when installation a new instance, i had missed to set the correct user under "Process Model" - Identity under Application Pools

Hello,

Thank you for your feedback @magnus01, it will hopefully help someone that encounters the issue!

@ksilva fixed the issue by re-applying the update and using the download option instead of using the .zip offline installer.

Best regards,

Hello Noah,

Thank you for reporting this issue.

Could you please verify in the DVLS application pool advanced settings in IIS Manager if the Enable 32-Bit Applications is set to False?



If that's already set to false, ensure that the service account designated as the Application Pool Identity in the DVLS application pool has enough rights on the App_Data subfolder in the DVLS web application folder.

Finally, ensure that the APS.Net Core module Hostin Bundle installed on the server where DVLS is hosted is at the latest version. Here is the direct download link to get it.

If you still get the 500.30 error after solving these, please open a ticket by sending an email to service@devolutions.net with reference to this forum's thread. We will then take over this issue in a support session.

Best regards,

Hello Erica
That was the solution -> i had to set "Enable 32-Bit-Applications" to False.
Thank you for your quick feedback.

You made my Day!

HI @Erica Poirier
I have the same problem, but no solution has helped so far.
When I want to install the ancm module, PowerShell tells me that it is installed, but the IIS web server shows it as not installed.

Need some help.....

Some More Infos:
If I switch the authentication on IIS to Windows authentication, I can only enter a domain user, not the previously created Devolutions Admin.
When I switch the authentication to Basic, the following error occurs:

The Module is already Installed:

Hello,
Since this is a rather old thread about an older version, it would be best to handle your issue separately.
I noticed you opened a new separate thread; we will continue the investigation there:
