Hey guys,

In an effort to try and save some resources on my primary Ignition server I offloaded all of the Kepware OPC stuff to the Backup server. However, after I did that a lot of my tags keep flashing with a “Bad” overlay. I checked out the console to see what was going on and I’m seeing these errors popping in very frequently:

This doesn’t make sense to me, I’m not sure what this means…

Both the Primary and the Backup server are virtual machines hosted by our cloud service provider. I’m running Ignition version 7.5.3 (b1163) if that helps. Is there anything that I can check to see what’s going on here?

Upgrade to 7.5.4 and they’ll go away. There’s now a 10-second window of forgiveness when the client checks the incoming timestamps. 7.5.3 had no window.

Yep, that looks like it took care of it. Wow, good timing. Haha! Thanks for the help! ![:thumb_left:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/e26afb081ddde6df016df6ee49159cf56aaca688.gif ":thumb\_left:")
