    • If you cannot do or don't know how to do the above actions, please contact our Live Chat Support. If not, then Windows or Antivirus Firewall, Windows Defender Firewall, Antivirus Firewall, ZoneAlarm etc.. to be turned off. (All Firewall either obstruct, slow down or do not allow any data flow at all as they check each and every quote that comes in. Sometimes they tend to block the data flow abruptly even after many days of smooth operations)
    • The data flow from velocity can stop working suddenly and without any warning because of being blocked by firewalls whose behavior and understanding of the data flow cannot be predicted
    • No Hardware firewall 
    • Recommended - > 'Allow apps to communicate through Windows Firewall or other Antivirus firewall'  (Firewall installed but off and apps not allowed has been seen to be causing problems in some cases also). All Antivirus firewalls to allow all these apps to communicate with each other or to be disabled completely.
