Sync Cloud - Sync Connection Failed - Network Port to open?

Good day,
I’ve setup Grindstone with cloud syn on my home PC and on my mobile phone - works great.

However, at the office i receive an error message:
“Grindstone Sync Connection Failed” -
“Might want to check your connection to the network. If this issue persists, please talk to your team’s administrator or contact Epiforge Support”

is it possible this app is using a special network port for synchronization to the cloud, and my company is blocking it?

Welcome to the forum, @bdamde!

Yes, it is possible your company is blocking the port, which is: 6457.
