Thank you for all of the information, @Aiky !
I used Google translate to read the message from your domain host, and the issue appears to be on their end; They mention your DNS settings contain a CAA record, which can be a reason for SSL issues. Therefore, I recommend contacting them directly and providing them with these DNS settings to have them adjust as needed.
If you are not seeing any ‘failed’ or ‘pending’ notifications about your SSL certificate from within your Shopify admin, then it has successfully been provided by us.
Let me know how it goes.
