I used your example code and it worked perfectly I was very happy because it's hard to find material with these examples. But after running it a few times, it started giving an error and it doesn't connect anymore, I didn't change anything. Error: Failed to start the server the launch of server DRC_GUI - workspace server for user j92211 failed Grid job failed to run. I have Sas Interprise Guide installed, and it is connecting and reading data normally. Do you have any idea what could be going on? Thank you very much your example helped me a lot.
