Controller fails for no apparent reason? Please help.

[parnell]

Hi, I'm a relatively new user (less than a year), but have over a dozen scheduled workflows that have been running without issue until this morning. When all my scheduled workflows vanished.

I went through the system settings (inside Alt) - no apparent changes. When I try to re-establish the controller, I'm getting this error message.

I can't seem to find any FAQ's or discussions where this has occurred.

Any ideas

PS - Win 7, Alteryx 10.6.8

Did you happen to change your Windows credentials recently?

That's usually the cause.  You would just need to update them in the System Settings.

Otherwise, check to make sure the AlteryxService is running (Task Manager --> Services --> AlteryxService).

If it isn't, restart it. 
I've seen it occasionally where a packaged IT update gets remotely pushed to machines and uninstalls this service.  You'd just need to reinstall it from the command line.  If you need help with that, there are several posts about it or contact Alteryx Support.

Hi Patrick.

Thank you for replying.

We found it - but oddly, it was a Skype port usage issue that was blocking the controller's ability to reach the web.

Might be valuable information for other users who run into this issue.

I had to turn off skype for auto starting when windows loaded. Then the controller can grab the port (80) for access and run properly. You can still launch Skype later - but not on start.

Hey @parnell

That's really interesting.  I wonder if you have some sort of custom configuration for Skype (didn't think it used 80 at all).  We also use Skype and never had a problem.

You may or may not already know, there are some options in Windows to change the execution order on start.

Alternatively, you can also change the port that Alteryx uses.  I've had to do that before when running other conflicting applications.
