SSL Certificate from Let's Encrpt

Our website: shows multiple certificates from let’s encrypt. Check out this link:

  1. The problem is, we don’t know, how many are actually required and how many we can remove from our there. Moreover, how to remove them?

  2. We have set TLS 1.2 and still our sites shows “Not Secured” before the URL. What is the reason behind that?

  3. I have gone through, and as it says, HTTPS is automatically attached to our subdomain also. But our website is showing 525 ERROR message. What should we need to do to get rid of this ERROR?

It would be appreciated, if anyone look into this and resolve it.

Thanking you in advance.

Kind Regards,

  1. These are just issued certificates, they are not necessarily valid any longer. You can leave it as it is.
  2. Mixed content. Search for these keywords here on the forum and you will find plenty of answers.
  3. On your server you wont have a certificate for that hostname. You need to fix your server configuration for that and install a valid certificate.

Hi @sandro,

  1. I have hosted my website on cloudflare. How can I fix it and install valid certificate?

Thank you

Cloudflare is not your host. You need to talk to your host about that and they need to deploy that certificate on their server.
