Hi John, great looking dashboard!!

I’ve had a look at the issue you posted above, and it appears to be an intermittent issue with the availability of http://solarschols.com/realtime.txt
More often than not, it’s available, but I’ve run some tests tonight and it appears to occasionally give a 404 error, which results in the error that you described.
The source of resultant 404 page is;

/* Copyright (c) 2018 Synology Inc. All rights reserved. */
(function(){var a=new XMLHttpRequest();a.open("get","/missing",true);a.send();a.onreadystatechange=function(){if(a.readyState==4&&(a.status==200||a.status==304)){var c=String(a.responseText);var e=document.open("text/html","replace");e.write(c);e.close()}else{var d={en:"The page you are looking for cannot be found."

It may be that the realtime.txt file is in the process of being re-written by your Synology software, at the same time as we are making a http request.

Could that be the issue?

Paul,

I did notice a couple of errors last night after I had reduced the number of item being fed. Since midnight however things have been running smoothly.

I’ll do some reading up and see if i can’t add an error check before updating.

Thanks for you time.

John
