Hi everyone,

I have a problem when I synchronize database:

System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
at System.Net.HttpWebRequest.GetResponse()
at Microsoft.Dynamics.Framework.Tools.ProjectSystem.DevFabricAccessor.StartWorkerProcess()
at Microsoft.Dynamics.Framework.Tools.ProjectSystem.DevFabricDebuggingHost.WarmupAppPool(Int32 RetryCount)
at Microsoft.Dynamics.Framework.Tools.ProjectSystem.Debugger.IISExpressDebuggingHostSupplier.InitializeDebuggingHostSupplier()
at Microsoft.Dynamics.Framework.Tools.ProjectSystem.Debugger.IISExpressDebuggingHostSupplier.RecycleAppPool()
at Microsoft.Dynamics.Framework.Tools.BuildTasks.SyncEngineWrapper.Sync(CancellationToken cancellationToken)

I tried Restart IIS, Server, Add Certificate, Full Build + Synchronize but the result was the same error as before.

How to fix?

Please help me!

Thanks & regards.

It suggests that the problem is about IIS Express, not IIS. Try restarting IIS Express (or Visual Studio).

Then try event logs; they might contain more details.

You can also try resetting IIS Express config as suggested here.

Hi Martin Dráb,

I checked event logs:

But, Certificates already exist in Manage Computer Certificates\Personal\Certificates and Expiration Date: 16/09/2020.

The log entry is about Management Reporter. I don't think it's related to your problem with database synchronization.

Hi Martin Dráb, hi Ludwig Reinhard.

I apologize for the late reply.

Thanks for your kind help.

As Martin Dráb says to restart IIS Express, in its basic case it solves the problem.

But our users reinstalled environment.

Thanks
