Periodic data loss

Hello everyone,

 

In my system I am running the PI UFL Connector that is requesting data every 10 minutes or so through an API. Strangely enough, since last week the system has been making periodic error. I notice that the machine cannot access the API. See a screenshot below of the data flow for the last one week:

 

Note the data gaps.

1st gap: 8/2/2020 14:30 - 9/2/2020 14:00
2nd gap: 10/2/2020 14:30 - 11/2/2020 14:00
current gap: 12/2/2020 14:30 - now; if my hypothesis is correct, at 14:00 today the system should start receiving data again.

I tried to access the API through the browser, Postman etc from the same machine and it does not return anything (connection timeout). However, accessing them from another machine outside the domain does return something. Any idea what's going on and how to solve them? Some periodic security processes blocking the connection maybe?

Any help would be appreciated!

 

Kind regards,

Tom
