Empty grey/gray error banner appearing at the top of Power BI report

[montanaBI]

Hi,

I have a report which is fed by direct query and the page is refreshed at 3 minute intervals. This same report is sitting on 4 different machines (with different filter configurations), these machines are are running 24/7 (with weekly restarts) .

My issue is, on a daily basis i will see a grey banner appear at the top of some (maybe all) of the report(s), this banner is normally used to display error messages, but mine are appearing with no text.

See below

How can i stop this behaviour, without having to manually remote onto the machines and 'x' out of the banner?

Thanks
