@redux-devtools/cli doesn't run on HTTPS after upgrade to 2.0.0

[GeneZharov]

Previously, I used version @redux-devtools/cli@1.0.7 and it worked fine.

I generated a local SSL certificate using mkcert:

mkcert \
  -cert-file local-cert.pem \
  -key-file local-key.pem \
  localhost 127.0.0.1 ::1

Then I run the Redux DevTools server using this command:

$ redux-devtools --hostname=localhost --port=8080 --protocol=https --key=local-key.pem --cert=local-cert.pem

[ReduxDevTools] Start server...

Then I open https://localhost:8080 and I see my Redux DevTools there.

But after I upgraded to @redux-devtools/cli@2.0.0 the output changed to this:

$ redux-devtools --hostname=localhost --port=8080 --protocol=https --key=local-key.pem --cert=local-cert.pem

[ReduxDevTools] Start server...

   [Done] Migrations are finished

And although there are no errors in the output if I open https://localhost:8080 the webpage is not opened and instead I see an error from Chrome:

This site can’t provide a secure connection
localhost sent an invalid response.
ERR_SSL_PROTOCOL_ERROR
