I upgraded to 2018.1 today. No other changes to my PC. Now I'm getting the ConnectNamedPipe: Error in ConnectNamedPipe The Pipe is being closed. I read that it could be security related, but I can't do anything to change policy and did not have the problem with the previous version. Wondering if anyone has fixed this. McAfee said Alteryx should submit to be whitelisted on their software package.
“Start: ConnectNamedPipe” Errors that occur when attempting to run the flow...at very beginning are in my experience due to security software like McAfee ATP (active threat protection). Keep in mind Alteryx is a "Load & Go" type of high level programming language that when you press "play" it runs a series of programs and snippets to transform your GUI workflow into a machine language executable form. These newer types of protection software, even when in "Observe" mode, will intercept and analyze all that activity to score it as a risk or not. This can at times cause delays in the interconnected events, thus ConnectNamedPipe error, basically a thread between 2 or more activities time out.
Another error we saw frequently before sorting this out is "Root Element Missing". this usually occurs when you open a flow and click on an input or dynamic input that has SQL. The issue here is the delay we are experiencing cause the initial DB query to get Table info failed, probably for timeout, and so you get a Root Element Missing error.
Be aware that errors “DataWrap2_ConnectNamedPipe after 11000 milliseconds” are a different issue, this seems to be a connectivity timeout, to NAS storage or some other data appliance.
The idea of a white list is to identify programs, files and or folders to exclude from the security program's process.
The attached pics are what we implemented with success for both Admin and non-Admin installs
Experiencing the same problem. Just got a new DELL that has McAfee pre-installed.
I looked for how to whitelist something in McAfee but couldn't find any useful information on the steps I would need to take or if it is even possible with a personal version (some indications that it is not).
For now, switching off real-time scanning (see screen shot) works, but that isn't really a sustainable solution. I will probably look for a different programme to replace McAfee but if anyone does have instructions on where and how to change the settings it would be appreciated.
All. I had this same issue when I upgraded from 2018.2 to 2018.4. It is definitely McAfee for me but there is no way to exclude the Alteryx program in their continuous scan. So, the solution ended up being uninstalling McAfee, running their repair tool, and reinstalling. That seemed to work. I hope this helps, and I hope McAfee gets it fixed on their end.
