Cannot register Azure Integration Runtime

Question

I am trying to register a self hosted Azure integration runtime. This used to work before, but suddenly the existing runtime could not connect anymore.

I already:

• Reinstalled the local runtime installation
• Removed integration runtime in Azure and created a new one
• Regenerated keys in Azure and tried key1 and key2
• Tried to install the runtime on another server
• Tried to use the Express setup from the 'Edit integration runtime' page

But when I try to register I always get the following error:

In the event log I get the following error:

Failed to get service token from ADF service with key ****************** and time cost is: 0.1628846 seconds, the error code is: InvalidGatewayKey, activityId is: 445deaef-dcd5-44c9-9123-703b81b35f3f and detailed error message is Processed HTTP request failed.
.

   at Microsoft.DataTransfer.DIAgentHost.NamedPipeControllers.NamedPipeGatewayClientController.AttachGatewayNode(String[] args)
   at Microsoft.DataTransfer.DIAgentHost.NamedPipeServer.MapNamedPipeRequestToController(String requestTemplate, NamedPipeStreamString ss, NamedPipeDataContract`1 result, String temp)
   at Microsoft.DataTransfer.DIAgentHost.NamedPipeServer.PipeServerThread(Object data)
.

So here there is mention of 'InvalidGatewayKey' and 'Processed HTTP request failed'

I couldn't find any useful information on these errors, so any help is greatly appreciated!

Finally the only solution was to create a new data factory and delete the old one. No idea why the initial suddenly stopped working.
