Getting UNAVAILABLE: Credentials failed to obtain metadata


I'm trying to create a chatbot that makes get the request to spring-boot application and spring boot application makes an API call to Dialogflow V2. I'm trying to access the Dialogflow V2 API via gRPC. I have created a service account and export service account key file and added it into the spring-boot application.

When I try to send a request to dialogflow from spring-boot application I have the following error:

I have tried that on personal network it works perfectly but when i tried on company network getting above error.

What should I do to fix this error? Any suggestions are most welcome.

Thanks in advance!


Solution

  • Check the system time on the machine where it's not working. Possible causes are: incorrect timezone, incorrect time in containerized or virtualized environments (e.g. clock on a VM and its host might not be in sync), or simply incorrect time.
