Very simply trying to perform a list query from my onprem Nintex workflow to SPonline. Not sure if Nintex needs to be installed on the online instance (it's not) but we do have an enterprise license on our on prem farm. Basically when trying to do a simple list query getting the below error message. Is there a way to fix this issue. Thanks to everyone in advance for your help.
