Subflow to clear cache doesn't seem to work, window not closing

[CharlesBrewer]

Hello,

So I have a flow that goes to a webpage, logs in and does what it needs to do. Every so often the login has an issue (an issue on the website's side, not something I can fix), that needs the cache cleared.  So on the step, I did the following error control : 

So the subflow it goes to looks like this : 

I am being extra cautious, but I assume what this should do is close all chrome windows with CMD prompt, then open up a chrome window to clear the cache, then close it.  The "launch new chrome" has the clear cache step : 

It sends me an email to let me know (for testing) and then I have it wait a moment to be extra cautious. It then, per the error control I assume, will exit the subflow and go to the "paccarlogin" label. 

After the paccarlogin (back in the main flow) is another CMD clear, for extra caution.  So the part that is not working, is for some reason a chrome window is still staying open. So the cache isn't getting cleared correctly and I just get stuck in a loop and 300 emails before I can get in in the morning and kill it.  Is there something I am doing super wrong? I don't understand why all the chrome windows are not closing.

I would usually use Terminate process instead of the CMD interface to do this. Also, you could do a loop and check if the Chrome process is running via the If process condition. And keep terminating it until it is no longer running, assuming that this only terminates one instance, where there might be several of them running.

What usually works for me to close Chrome is a sub-flow that closes the window by using Close window via the window title (with * as a wildcard to ignore the page title) and class. Then waiting for the process to stop via Wait for process with a timeout, and checking if the process is still running. Ff it is, then I terminate it.

Thanks for the response. I believe the taskkill "should" kill all the windows/processes, unless I am doing it wrong. I've tested it though with multiple chrome windows open and it does close all of them. That's why I am confused that a window seems to linger open, thus cache is not being cleared very well. However for testing purposes I added this after the CMD taskkill (I'll get rid of it later if it seems to work).

Does this look like what you mean? I tested just the If process and it seems to be working....but so does the CMD one so, who knows.

[Agnius]

More or less, but I would also add a Wait for process action before the If process, so that it waits for Chrome to close completely before continuing. Set it to have a timeout of some seconds and make it continue to the next action on error. This way it will wait a bit after your taskkill command and then check if the process is still running.

Will do! It's hard to test I'll just wait until it breaks again and hope for the best, thanks for the recommendations.
