It's now jumped up to 453 excluded pages.
Couple of things to note:
1. The site is an old site on a new domain.
2. It's all good quality content
3. Google console is pulling
https://www.
4. There are 3 results listed in Google all are www.
5. Robots.txt looks fine
6. .htaccess looks fine
7. I tried to run a googlebot checker from a random website and got a 302 blocked error but this could just be a false positive because I can access pages fine
8. It's wordpress. I have disabled a lot of the plugins that I think could be causing an issue
