Resolution

To resolve the issue, the following steps were performed.
1. Navigate to C:ProgramDataSourceCode (ProgramData is a hidden folder) on your local machine that has K2 thick client tools installed.
2. Open up the configurationmanager.config
3. Check the values under the tag, there might be an incorrect entry (i.e. Server name is wrong), change server name to use the IP address 172.xx.xx.xx.
4. Find the UserBrowserServer section, and add the following connection string
<settings>
<add key="UserBrowserServer" value=" Integrated=True;IsPrimaryLogin=True;Authenticate=True;EncryptedPassword=False;Host=server_ip_address;Port=5555;SecurityLabelName=K2;UserID=account_name;Password=password;WindowsDomain=Domain_name
" />
</settings>
5. Edit the Workflow Management Server(s) from K2 Object Browser > Environment > Workflow Management Server and modify the connection string to use the K2 server’s ip address.
