Rumba+ Teminal Session

Hi,
I’m having an issue with the Terminal Session for Rumba and getting the error below


Do you have any configuration/connection setting to fix this isse?

This is the connection String I am using
“{‘AttachExisting’:false,‘ConnectionProtocol’:0,‘ConnectionType’:2,‘EhllBasicMode’:false,‘EhllDll’:‘C:\Program Files (x86)\Micro Focus\RUMBA\System\ehlapi32.Dll’,‘EhllEnhanced’:false,‘EhllFunction’:‘hllapi’,‘EhllSession’:‘B’,‘EnableSSL’:false,‘Host’:null,‘InProcessMode’:false,‘Mode’:1,‘Port’:23,‘Profile’:null,‘ProviderType’:4,‘ShowTerminal’:true,‘TerminalModel’:0,‘TerminalType’:0}”
