Certificate SSL via Instagram settings

Good day to you,

I have an SSL certificate from you on my website kurzysitia.sk, it works well and correctly.

I recently created an Instagram account for my website and I also set up an account on lnk.bio.

I have set this same link as a link on IG in the settings, only if I open this link via Instagram on mobile, it gives me the following error:

Security Error
There are problems with the security certificate for this site

Please, advise me what I should do to make it work properly on mobile as well.

Thank you.

When you opened this thread in the Help section, you should have been provided with a questionnaire. Maybe you didn't get it somehow (which is weird), or you've decided to delete it. In any case, all the answers to this questionnaire are required:

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

I don't know the answers to all the questions. However, I would like to get an answer to my problem. What category should I choose for my question, please, so that I don't have to answer these questions?

If you don't answer those questions, no one will have the information required to help you.

The problem you describe sounds like an Instagram defect, not a Let's Encrypt issue.

See of this external discussion of identical symptoms has anything that helps.


Thank you.
