Did you recently work with SSL on the site? For example, enable SSL or possibly change the certificate?
I’m seeing a few errors within the Router Log that appear to be related to NGINX not being able to make a secure connection:
2021/11/23 00:28:27 [crit] 16940#4388: *7 SSL_write() failed (10053: An established connection was aborted by the software in your host machine) while sending to client, client: 127.0.0.1, server: moleli-high-school.local, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:10004/", host: "moleli-high-school.local", referrer: "https://moleli-high-school.local/"
You might be able to do a search and replace on the database and change the site back to using regular HTTP. That process is most easily done with wpcli within a terminal. Right-click on the site in Local and select “Open Site Shell”. From there, you should be able to do a search and replace with this command (being sure to double check that the domain is the correct one for your site!) Also note that the only difference between those two domains is that one has the
wp search-replace 'https://example.local' 'http://example.local'
Let us know how it goes!
