Dude , changing your SiteURL & WordPress URL from the Admin Panel will not change anything until you shift the contents of your blog folder to the root directory..
You can redirect https://www.gregtassone.net/blog to https://www.gregtassone.net/ by configuring Permanent 301 Redirect by editing your root .htaccess file.

Then add them , but I don’t think the problem is there with your SSL , I think you will have to re-install..

Can you access your web server via FTP? If yes then manually download the wordpress package & overwrite it with the default installation , this might fix the problem ,since the posts & stored in the database , nothing will be deleted.

I checked it & the domain https://www.gregtassone.com does not contain anything or file , I suggest you to wait for atleast 48 hours then check it back.

Tell your full website & goto to the updates option from your Admin Dashboard & click on update or Re-Install WordPress , Don’t worry , It will not delete your posts as I have also tried it.

Hello There!
I didn’t find problems with your DNS records but one of your nameservers (ns3.unoeuro.com) is not responding , it might cause a problem so you should check with your hosting provider.
You should also try to minify the html , css & javascript because sometimes it can result in a slow site.

Try these steps which might increase the performance of your site-
1. Choose a good host
2. Use an effective caching plugin , e.g W3 Total Cache
3. Use a Content Delivery Network (CDN) – I personally recommend CLoudflare , It also has a free plan with SSL for all customers for free.
4. Optimize Images – You can use a plugin , e.g. WP-SmushIt
5. Optimize your WP Database – You can use a plugin , WP-Optimize
6. Disable hotlinking and leeching of your content – Place this code in your root .htaccess file without quotes

“disable hotlinking of images with forbidden or custom image option

[ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]

RewriteEngine on
 RewriteCond %{HTTP_REFERER} !^$
 RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?sparringmind.com [NC]
 RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?google.com [NC]
 RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?feeds2.feedburner.com/sparringmind [NC]
 RewriteRule \.(jpg|jpeg|png|gif)$ – [NC,F,L]"

7. Add an expires header to static resources-
Place the following code in your root .htaccess file

ExpiresActive On
 ExpiresByType image/gif A2592000
 ExpiresByType image/png A2592000
 ExpiresByType image/jpg A2592000
 ExpiresByType image/jpeg A2592000
