MeteoTemplate API working sporadically

Version 10.37S119

For the past couple of months, when I exit WD and reopen the application, it doesn’t appear to execute the MeteoTemplate API. If I click the “test” button, it will immediately update my website but will not continue to update as scheduled (every 5 secs). Sometimes, 45 minutes later, it will just start working (if I’m lucky). I’ve tried using other browsers, clearing the browser’s cache, re-booting my computer - nothing appears to help until it just starts working again. Is there an error log or program log that may get written to if something is preventing the API from being invoked in WD?

Thanks in advance for the assist.
