about AskTimeoutException

[fix-all]

hi,

The Gateway service calls the Things service and reports an error "org.eclipse.ditto.base.model.exceptions.AskException: There was an internal timeout." The specific error is as follows. I am using Ditto version 3.1.2. How should I troubleshoot this problem?

I would suggest to update to a supported version of Ditto and check if all the services are running or if some eg crashed, eg due to too less resources.
