Hi there - Kristina from Moz's Help Team here. Just as the helpful responses stated before mine, unfortunately at this time our crawler isn't compatible with Server Name Indication (SNI), which appears to be in use on your site (https://www.kitchenstuff.com). In general, SNI is a totally acceptable security configuration, but our crawler simply isn't equipped to be able to handle these settings.
If you are able to disable the SNI configuration on your site, then we should be able to crawl it normally. While it's something that we'd love to be able to accommodate for the future, we don't yet have the resources to be able to make those changes.
Also as mentioned previously by Dirk, this thread in our Community Q&A forum with lots of other users running into the same problem, so it's definitely something we're aware of and working to address: https://mza.bundledseo.com/community/q/804-https-ssl-error
We're sorry about the trouble & inconvenience this causes.
