Hello Luna,
You can check the following steps for some troubleshooting tips:
1. On Linux, make sure the agent is installed as a root user or with the sudo commands.
2. Make sure you included the flag --write-gcm on the install script
3. If you installed private-key credentials on your VM instance, be sure the credentials file is stored on the VM instance in the correct location. More information is available in this Help Center
article.
4. What is the error message you are getting while trying to access the account configuration?
I hope this helps.
Sincerely,
George
