One reason for an Internet Communication Interruption error might be a firewall blocking traffic from the DC box device to Petrosoft cloud resources. If the DC Box is operational and physically connected to the network, but still cannot connect to CStoreOffice®, check and adjust outbound firewall rules to allow communication with the required cloud services.
We do not limit the type of firewall you use at your locations. You may choose any software and hardware solution depending on your needs and IT policies. Each firewall is configured individually through a web interface, command line, or external application - check the instructions for your specific solution for details on configuring the rules.
For proper functionality, DC Box relies on both Petrosoft services and services from third-party providers. See the information below for details on configuring firewall rules.
Configuring firewall rules for Petrosoft service access
The easiest way is to allow outbound access by wildcards. However, if you still have connectivity issues, or the firewall or your IT policies require stricter access control, you can separately configure each DNS or IP address.
Using wildcard FQDN addresses
We strongly recommend configuring firewall rules through wildcards:
