yii2: Not Found (#404): Unable to find debug data tagged with '55ede6f2ba13e'.

Im keep getting the same error on every page, even after clearing the runtime and the asset folder. The debugbar is also delayed (5 seconds), when it appears the message is: “Not Found (#404): Unable to find debug data tagged with ‘55ede6f2ba13e’.”.
