Context
- I try to develop a ServiceWorker for my Website
- The ServiceWorker registration fails because of my untrusted (self signed) cert
- The url I use locally is https://mypage.local
What I tryed to let my browser trust my cert
- starting chrome with flags like --ignore-certificate-errors --unsafely-treat-insecure-origin-as-secure=https://mypage.local/ --allow-insecure-localhost
- create a root CA and install it as trusted CA in my OS (windows)
- create a new server cert with that root CA and use it for the local website (the new cert is delivered)
- Firefox tells me SSL_ERROR_BAD_CERT_DOMAIN. I added SAN entries in addition to the CN to the cert
- I verified my cert via https://www.sslshopper.com/csr-decoder.html and the fields are correct
The cert is still not trusted, I still get the SSL_ERROR_BAD_CERT_DOMAIN in Firefox
Any idea what I still do wrong or how I can debug my issue further?
