From 24H the adv not loading banner, but this code on my application, android and iOS... I don't understing what is that

{"ad_type":"banner","qdata":"AJ5UM1laXk7AWlBDddkiA0RwP33uiKxcDKm3QEYCtMJjMgOwsyd6xIP7ZJXw3w6msYzyCCaLI0L-LuUq6glbb9Ae_e4WGBQUdxV5kseStPdi1a7s6g","settings":{"click_urls":["http://e.admob.com/clk?qdata=@gw_qdata@&js=@gw_sdkver@&session_id=@gw_sessid@&seq_num=@gw_seqnum@&adt=@gw_adt@&aec=@gw_aec@&ad_network_id=@gw_adnetid@&allocation_id=@gw_allocid@&nr=@gw_adnetrefresh@&client=ca-app-pub-109109109101&slotname=1917213385"],"imp_urls":["http://e.admob.com/imp?qdata=@gw_qdata@&js=@gw_sdkver@&session_id=@gw_sessid@&seq_num=@gw_seqnum@&adt=@gw_adt@&aec=@gw_aec@&ad_network_id=@gw_adnetid@&allocation_id=@gw_allocid@&nr=@gw_adnetrefresh@&client=ca-app-pub-109109109101&slotname=1917213385"],"nofill_urls":["http://e.admob.com/nofill?qdata=@gw_qdata@&js=@gw_sdkver@&session_id=@gw_sessid@&seq_num=@gw_seqnum@&adt=@gw_adt@&aec=@gw_aec@&client=ca-app-pub-109109109101&slotname=1917213385"],"refresh":60}}

My suspect is that this error is connected to the autopromo banner
