Getting Error: Unable to navigate to the URL/page while launching tests

I am unable to execute my tests when launched through a Jenkins job. Please find the environment details below:

TestComplete (Server): 14.81.217.7 x64
TestExecute (VM): 14.81.217.11

Chrome Version (Server): 91.0.4472.77
Chrome Version (VM): 91.0.4472.77

License Details:
TestComplete 14: node-locked
TestExecute 14: floating, 1 seat

Job Details:
Run interactive user session is turned ON and running a specific project suite.

Node Details:
Launch method: Launch agent by connecting it to the master
Internal data directory: remoting

Scenario 1:
Launch the VM through RDP session from the server machine and run the Jenkins job by keeping the VM session active then my tests will run. I can see the tests running through TestComplete chrome plugin.

Scenario 2:
Disconnect the VM and then run the jenkins job, after few minutes jenkins job will be marked as failure and I see following logs:

I have manually launched the Jenkins agent through jnlp file and kept the console open to run my tests.

Appreciate your response on this.

Thanks!
