Every couple of minutes I get this log from COMSubscription on my gateway that says  
`[tag-group-default_default] Failed to add 140 items to the subscription- error codes were returned from the OPC server. To see the codes, change the log level to debug and re-initialize the items.`

If I debug I can see the 140 errors that each look something like this.  
`Failure code returned from OPC server when adding item to subscription. Path: 'ifm.VSE.DBPskid4.Monitoring.Objects.Object06.Condition' Return Code: 'ffffffffc0040008'`

[tag-group-default\_default] is not a tag provider on our gateway. I found another post talking about this issue [here](https://forum.inductiveautomation.com/t/tag-group-failed-to-add-x-items-to-the-subscription/27951).  
They get around this bug by deleting all of their tag providers, and manually re-adding each tag to the new providers, but I'd rather avoid this as we have so many tags and scripts referencing those tags that it would be a pain to try to re-do. Any tips on how to get around this? Thanks!
