Hey there,
I'm Marco from Spreaker. We're your customer and we've a CNAME that points to We're currently migrating all our traffic from HTTP to HTTPS and we'd like to migrate TenderApp to HTTPS as well. Is it possible to configure a custom SSL certificate on your service, so that will work?

    Marco -

    No, Tender does not support SSL on custom domains at this time.

    Let me know if you have any question.

    This is because only some browsers support the necessary technology for cnames (SNI). The easiest way for you to do this is to set up a proxy (reverse proxy). You would host the ssl cert and just proxy to (which already has ssl).

    Thanks for the reply.

    For the sake on truth, most browsers currently support SNI. Ie. our
    CloudFront CDN has SSL configured via SNI and we actually got *no issues*
    (1M requests / day).

    Hi there,

    I'm following up this discussion, to check if there's any change on your side, to support custom SSL certificates. Do you have any plan to add it? (please be honest, because we'll outline our 2017 Q1 roadmap according to your answer)

    Thank you,

    Hi, yes, we can now install a custom SSL certificate on our end. You will need to adjust your IP address with dns once it's running.

    That's a very good news. Few questions please:

    1. How can I upload the custom SSL certificate?
    2. Does it come at the same pricing?

    yes, just send me the files, we don't have an automated system for it.

    That's a great news!

    We would like to generate the certificates with This means
    certificates will expires in 90 days, and thus every about 75 days you will
    be asked to change our certificate (we'll send you an automated email every
    75 days with the new certificate). Is this workflow feasible to you?

    An alternative to us, could be try to setup AWS CloudFront CDN in front of, but I'm not sure everything will work fine.
    Do you have any experience with such setup?

    Hey Marco, sorry for delay. Other customers have had success with cloudfront CDN. It should work fine, and would let you control the certificate yourself. (We use cloudfront for our asset hosting)

    Do you support the X-Forwarded-For header? If not, the remote IP you detect is the the CloudFront edge IP and not the real client IP.
