This placement stopped receiving impressions in the last 3 days

Hi, I have an app with Unity ads that were displaying correctly, but a few days ago the ads stopped showing. When I checked the ad placements, a yellow dot appeared next to the ad with the following note: This placement has stopped receiving impressions in the last 3 days, although I have a similar app with the same settings and the ads are showing normally, is there an explanation for this issue?
Note: The app is working with users.
In android studio log shows this error:
