Phase 3 - Transferring files to the FTP area

Q: In trying to upload my files to the phase3 ftp I encountered an error message, how can I proceed?

The error is caused by FileZilla not trusting the OS certificate stack. In order to proceed, you have to confirm explicitly that the server can be trusted. Having verified that the server’s fingerprint and the certificate fingerprint displayed in the figure are identical, please accept the server certificate by checking the two options as shown in the figure below.
