Problems with banner display

[Lubrick]

Hello,

I noticed a problem with AdServer and could use your help. On some mobile devices, on Android and iOS apps AdServer does not display banners due to an unknown error. However, this problem is not persistent and it manifests randomly.

A way to reproduce the issue would be to click on a link to some banner in Chrome or Firefox mobile browser incognito windows (also noticed on desktop incognito browsers)

Banner link has this format:
http://www.example.com/mobile_banner_43.html

On first click banner is not loaded, but it loads after a refresh.

While testing I put these variable values in javascript console "OA_output['320x50']" and on first call it returned no value, but after refreshing the page I got a response.

Here are responses for first and second call by the adserver, that returned different responses.

 

FIRST CALL:
 

var OA_output = new Array(); 
OA_output['320x50'] = '';
OA_output['320x50'] += "<"+"div id=\'beacon_5ac77bf265\' style=\'position: absolute; left: 0px; top: 0px; visibility: hidden;\'><"+"img src=\'http://ads.example.com/www/delivery/lg.php?bannerid=0&amp;campaignid=0&amp;zoneid=43&amp;source=Main&amp;loc=http%3A%2F%2Fwww.example.com%2Fmobile_banner_43.html&amp;cb=5ac77bf265\' width=\'0\' height=\'0\' alt=\'\' style=\'width: 0px; height: 0px;\' /><"+"/div>\n";

 

SECOND CALL:
 

var OA_output = new Array(); 
OA_output['320x50'] = '';
OA_output['320x50'] += "<"+"a href=\'http://ads.example.com/www/delivery/ck.php?oaparams=2__bannerid=6334__zoneid=43__source=Main__cb=1f321f9d78__oadest=http%3A%2F%2Fsubdomain.example.com%2Fwebsite-section%2Farticle-url-and-id\' target=\'_blank\'><"+"img src=\'http://ads.example.com/www/images/7da719d964bb4d6311c9dada6cb6f229.jpg\' width=\'320\' height=\'50\' alt=\'\' title=\'\' border=\'0\' /><"+"/a><"+"div id=\'beacon_1f321f9d78\' style=\'position: absolute; left: 0px; top: 0px; visibility: hidden;\'><"+"img src=\'http://ads.example.com/www/delivery/lg.php?bannerid=6334&amp;campaignid=3618&amp;zoneid=43&amp;source=Main&amp;OAZBLOCK=3600&amp;OAZCAP=99999&amp;OASZCAP=99999&amp;loc=http%3A%2F%2Fwww.example.com%2Fmobile_banner_43.html&amp;cb=1f321f9d78\' width=\'0\' height=\'0\' alt=\'\' style=\'width: 0px; height: 0px;\' /><"+"/div>\n";

Could you please help me understand why is this happening, I am out of ideas. Thank you very much.

No ideas from anyone?

Do you have delivery capping for the campaign or banner?

[Lubrick]

Yes, as it turns out the delivery capping was set to some value, instead of "unlimited"... :/

Thank you very much for your help and sorry for wasting your time.
