    Why is my website inaccessible?

    There are three possible reasons and you need to troubleshoot accordingly.

    The common website cannot Access for the following reasons. If you fail to solve your problem in time, please pass the Submit a ticket Contact Us.

    Reason 1: The website has not obtained ICP filing yet

    To use servers in Mainland China to set up a website, you must first apply for ICP filing, and the website can be launched for access only after the ICP filing number is obtained from the communications administration.
    For the specific reasons for the need for ICP filing and the influence of ICP filing, please refer to Overview . You can submit an ICP filing application in the ICP filing system of the server provider. Guide for ICP filing application through Tencent Cloud:

    Reason 2: The website's ICP filing has not been transferred to Tencent Cloud

    If your website has obtained an ICP filing through another access service provider and now you want to switch from your original provider to Tencent Cloud, you need to transfer the ICP filing to Tencent Cloud and only after that can you engage in website content services through Tencent Cloud.
    To understand why ICP filing transfer is required and the detailed application process, see Quick Start for ICP Filing Transfer Application.

    Reason 3: Your website's ICP filing number has been deregistered.

    Possible reasons why an ICP filing number is deregistered include the following. For the specific reason, please contact your local communications administration.

    1. ICP filing entity applied for deregistration directly to communications administration or via access provider:
      The domain name is no longer owned by the entity; the entity no longer engages in website business; or the entity is changed or dissolved.
    2. The domain name has expired and the new domain name owner submitted an application for deregistration to Communications Administration Bureaus due to domain name conflict:
      The domain name with ICP filing number has expired, but the new domain name owner couldn't submit an application for ICP filing (due to domain name conflict), so they submitted the domain name certificate and explanatory note to the provincial communications administration to apply for deregistration of the ICP filing, which then deregistered the conflicting domain name's ICP filing after verifying the actual conditions.

    In this case, if there is only one website under the name of the entity, the entity will be deregistered; if there are multiple websites, only the website with the conflicting domain name will be deregistered, while the ICP filing information of other websites will be retained.

    1. The website information is false or inaccurate, or some information is missing in the ICP filing:
      1. In most cases, the reason why the access provider cancels the access is that the user no longer engages in website content services on the registered platform and stops using the servers of the access provider; after the access is canceled, the website becomes an empty shell and will be deregistered by Communications Administration Bureaus.
      2. The website information is false or incorrect, for example, the phone number in the ICP filing information has been changed or canceled, and if this is found during the spot checks by Communications Administration Bureaus or MIIT, deregistration will be performed.
        Communications Administration Bureaus will deregister a website containing illegal information and its entity. In serious cases, the entity will be blacklisted and prohibited from re-applying for ICP filing with its identity document number or website name.
