VAST tag url error: Ad error: AdError 1012: Unable to request ads from server due to network error

I have created a VAST xml version 2 which follows the proper standard. I am trying to validate it in vast tag validator

There are two options in the validator. Either to upload VAST tag or VAST XML. I paste the VAST tag (i.e. the link to the xml file) it gives me this error

Ad error: AdError 1012: Unable to request ads from server due to network error.

However, when I paste the xml itself into the VAST xml field option, the ad runs perfectly fine. I cannot share the xml because of security reasons. Is there a way to tell what possibly could be the problem?

IMA Inspector throws that error for example if you tag does not deliver via HTTPS. In case you did use HTTPS, could you share the tag? – Zero2
@Zero2 I tried both http and https....gives me the same error. I can actually share an alterated tag not the actual one cos of security issues if that would help – Red Bottle

I reproduced (10:51:46) Ad error: AdError 1012: Unable to request ads from server due to network error. issue.

After review of console errors I figured out the issue was related to CORS.

Console when use VAST tag

Then I added https://imasdk.googleapis.com to allowed origins list of my API and the issue was solved. Hope this is the root cause for you as well
