NET::ERR_CERT_AUTHORITY_INVALID in Chrome not incognito and Firefox locally with valid certs on nginx
I have some great news!
We're using the same cert on our cloud dev environments (however, they are in pfx form). Locally I run Linux as mentioned, and I had to convert the pfx to a RSA file and a CRT file.
I entered our dev domain on this site: https://whatsmychaincert.com/ and it downloaded a *.chain.crt file. Together with my old crt file, and this command:
cat example.com.crt example.com.chain.crt > example.com.chained.crt
In Nginx I then referenced the .chained.crt file.
Now Chrome accepts my local, secure webpage.
