How do I use a wildcard certificate with subdomains?

    I have a Plesk for Windows 8.6 account with a shared hosting provider. I am a Plesk account user - I am not the Plesk administrator.
    I am trying to work out a way to use my wildcard SSL certificate with subdomains created via the Plesk console.
    The admin of the Plesk installation does not appear to know how to do this - so I am trying to work out a sequence of steps that myself and/or the admin can perform to make this happen.

    For example:
    I have a domain www.mydomain.com that resolves to a static IP number.
    I have a wildcard certificate for *.mydomain.com.
    I have a subdomain named test.mydomain.com (either with physical hosting or as a sub-directory - I don't care).

    What I would like is to be able to navigate to https://test.mydomain.com and load documents stored in the httpdocs (or httpsdocs) directory or sub-directory of the of the subdomain via an SSL connection.
    I would like to be able to do this without having to do host-header detection via scripting on the parent domain if at all possible.

    Just to give a bit more background - I run a software development company.
    I would like to have my own website at www.mydomain.com (ie: ticket system, brochure-ware, etc) and have test sites for my clients on subdomains (eg: abc_company.mydomain.com) that resolve to the clients own site that I have developed.

    There does not seem to be a way of doing this via Plesk.
    Am I missing something?

    Any tips appreciated.

    WildCard SSL Certificate

    Hello Yog,


    Wildcard SSL certificate installation is quiet easy and bit confusing. How to get wildcard SSL?

    1. Login to Plesk panel and select domain
    2. Click on SSL Certificates
    3. Request Cert :
    Here use domain name *.domainname.com (Here '*' is sign of wildcard)
    4. Copy CSR key or get Key email in your mailbox
    5. Buy wildcard SSL from SSL provider (Use CSR key generated from Plesk)
    6. Install / upload SSL certificate key on Plesk.
    7. Set *.domainname.com certificate as default certificate.
    8. Use this SSL certificate for all of your sub-domains security.

    Here is few of WildCard SSL Providers

    RapidSSL, Thawte, Comodo, GeoTrust, InstantSSL

    Wildcard SSL in Pleask for subdomain

    Hi there,

    I have purchased a wildcard SSL and installed in pleask under the domain (e.g domain.com)

    I have few subdomains (e.g test.domain.com). I cannot find a way in pleask to apply the SSL to the subdomain.

    The main domain and subdomain are using the same IP address

    When i try with https://test.domain.com it shows the page in https://domain.com

    Could you please provide some help in fixing this issue

    Notes: I uploaded the SSL to under the respective domain not under Home > SSL certificates

    Wildcard SSL Certificates are a great way of linking and securing subdomains. Wildcard SSL Certificates are available from numerous certification authorities such as Thawte, GeoTrust, GlobalSign and RapidSSL. Numerous resellers should provide you with the necessary support and advice to successfully installing these certificates. Otherwise going back to the certification authority will also provide you with this information additionally.

    It isnt possible to use SSL on a subdomain set up within the "Subdomains" section.

    However, you can create the subdomain at the "domains" level and you can then set up SSL this way. You would need a dedicated IP for each subdomain so it may not be possible depending how many IP's you have available.

    wildcard certificate with subdomains

    Hi Guys

    I have already bought a wildcard SSl certificate for *.mydomain.com and it is working fine.

    Now I have a subdomain called test.mydomain.com and I need a wild card SSL for this subdomain like *.test.mydomain.com

    Both are going to be different certificates working in different IPs

    Please let me know if it is possible to get *.test.mydomain.com to work with https.
