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:UsersFrank.neo4jknown_hosts`.
The old certificate saved in file is:
-----BEGIN CERTIFICATE-----
2bbc81688243fcb25943f8928f455c5bba6f3e623e9d8616d5be95051c96dffe

-----END CERTIFICATE-----
The New certificate received is:
-----BEGIN CERTIFICATE-----
2bbc81688243fcb25943f8928f455c5bba6f3e623e9d8616d5be95051c96dffe
