There are a number of reasons the Campaigns will show the status as “Terminated”.   Complete the Campaign once it’s been opened – the offer will most likely ‘time out’ if the deadline is passed and will be deemed as Terminated.   Only use one device – make sure you login and execute a Campaign on the same device that you started it on; if you try and carry on a campaign on a different device, the EOS portal or the GCN Tool will identify it as a duplicate activity and that may result in the Campaign being terminated.   Use a valid internet connection – if you’re using a VPN or proxy, please make sure you turn it off before logging into the EOS portal and activating the GCN tool.
