FTP Failure

(1/3) > >>

wx-watch:
I have been running the Weathercat on a Mac mini without a problem for a year now. WeatherCat is the latest version and the Mac mini is running Mojave with all the latest updates. However twice in the last week I have had an FTP problem. My web page wx-watch.co.uk fails to update and looking at the log it says FTP failure, site may be down. It isn't as I can connect to it via an FTP client. No details have changed as far as my account is concerned. Updates to other sites like Wunderground and the Met Office are unaffected. Simply restarting Weathercat (not the Mac mini) resolves the problem.

Any ideas?

Unfortunately there isn't any obvious explanation for this sort of phenomenon that I'm aware off.  The only thing I've noticed with Mojave is that the operating system itself can behave strangely after allowing it to run for an extended period of time.  In my case, I have an external USB hard drive that is used infrequently to store larger videos.  After about 20 days, that drive starts to be mysteriously and spontaneously disconnected.  If I do nothing the problem repeats.  If I reboot the drive remains connected to my computer.

So if your Mac mini has been running for an extended period of time on Mojave, you might try rebooting and see if that clears up the problem.  WeatherCat uses the external utility curl to actually perform the FTP upload, so it is more vulnerable to Mojave than one might expect.

So then I wonder if the way forward is to get the Mac Mini to restart once a day using its schedule function? That way I don't need to keep checking to see if has stopped uploading my data.

Or is there anyway to get WeatherCat to restart itself if FTP uploads fails (as I said simply restarting WeatherCat manually fixes the problem)

Blicj11:
WeatherCat does have some capability of restarting itself. In Preferences on the Units/Misc 1 tab, in the bottom left corner, is a box labeled Monitor & Re-launch WeatherCat. When this box is checked, WeatherCat runs a separate process called WatchDog. However, in my experience, WatchDog only restarts WC when WC hangs. I have had several experiences where FTP did not work for quite a while when my site was down and WatchDog did not restart, or if it did, it was hours before it kicked in.

It seems to me that your easiest temporary workaround is what you suggested: Reboot the Mac once a day. But If you use the macOS schedule function to do this, make sure that:

* WeatherCat is in your Login items so it runs at startup
* WeatherCat Preferences | Advanced | Quit Check is NOT checkedThis will only work if you have enabled Automatic login in your macOS Settings because WC doesn't startup until you are logged in. If you are running Mojave, read this: https://discussions.apple.com/thread/250389991

Thanks.

WeatherCat is in my Login Items and the Mac Mini is set to auto login.

Why is this needed

?WeatherCat Preferences | Advanced | Quit Check is NOT checked?

As when I reboot manually all is well with this checked
