Welcome to the Q&A Forum

Jennifer, Some of your pages still reference http images - example https://www.tsheets.com/proadvisors-we-trust.php calls image http://cdn.tsheets.com/images/pros/denise-loter-koch.png "Your connection to www.tsheets.com is encrypted with obsolete cryptography. However, this page includes other resources which are not secure. These resources can be viewed by others while in transit, and can be modified by an attacker to change the look of the page." This is probably the reason for the 804 errors in Moz. You should also check your internal links - some of them still point to the http version which is then again redirected to the https version Example https://www.tsheets.com/infographics/time-tracking-infographic-hr-industry links to http://www.tsheets.com/infographics/time-tracking-infographic which is then redirected to https. Unrelated to the https - but you might want to optimise the image on https://www.tsheets.com/online-invoicing-and-billing/ (https://www.tsheets.com/online-invoicing-and-billing/images/main-image-billing.png) rgds Dirk

Don’t really want to add anything more, the one word answer to your question is “Screaming Frog”! Hope this helps!
