Caused by: java.security.cert.CertificateException: Unable to connect to neo4j at `localhost:7687`, because the certificate the server uses has changed. This is a security feature to protect against man-in-the-middle attacks.

If you trust the certificate the server uses now, simply remove the line that starts with `localhost:7687` in the file `C:\Users\Frank\.neo4j\known_hosts`.

The old certificate saved in file is:

-----BEGIN CERTIFICATE-----

2bbc81688243fcb25943f8928f455c5bba6f3e623e9d8616d5be95051c96dffe

-----END CERTIFICATE-----

The New certificate received is:

-----BEGIN CERTIFICATE-----

2bbc81688243fcb25943f8928f455c5bba6f3e623e9d8616d5be95051c96dffe
