Gateway connection Failed

Hi everyone,

I am facing the following problem and would like your assitance:

My Materials Studio client machine is not connecting to the gateway of the server machine to be able to run jobs. Whenever I try to connect to the gateway the following error message occurs (as in the screenshot)

Through services, I have checked that the gateway service is running on the server side. I have confirmed that the gateway name and port are correct as well. Default Port 18888 was also successfully pinged and checked that it went through firewall security.

Kindly let me know if I have missed anything in the troubleshooting process. The server is a virtual machine, could this be the reason for this error?
