Zoom on prem

[FitraArganata]

Our company is starting to deploy zoom meeting on premise. Before we deploy it on our premises, we need to set the poc first. To avoid several security requirements, we decided to deploy it on cloud(gcp). The deployment is successful but when we need to start the meeting on premise, we are facing zoom error 104103. Did anyone have the same problem when deploying zoom on premises on gcp platform? Kindly need anyone help
