Guide - JS/CSS assets are returning 403 errors

    We found that the Zendesk server (or CDN) is blocking requests from this user agent (google bot).

    We have been able to reproduce the http request that fails:

    The url of the asset (any asset that fails) is the same, the only thing is that the user-agent should be: Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.96 Mobile Safari/537.36 (compatible; Googlebot/2.1; +

    Seems like + at the end is the reason of the issue.

    When this is sent, instead of receiving the asset we receive this message:

    An action you just performed triggered a security alert and blocked your access to this page. This could be because you submitted a SQL command, a certain word or phrase, or invalid data. 
    If this continues to happen, create a HTTP archive file (follow this tutorial) with the issue reproduced and send the file to us.

    Has anyone experienced the same and has it been possible to adjust on Zendesk's end?
