Old SSL certificate still being served after renewing it

My new certificate (created with gitlab-ctl reconfigure) is not showing up as being renewed in browser. I had moved my old cert and key into another folder, and then compared the old one to new one, and yes they are different.

I’m not too sure why nginx is having an issue binding to port 80… could this possibly be the issue?
Any help here would be greatly appreciated, thanks!
