Cannot connect to perforce server in 4.10 preview 3

Sorry if it was confusing, the editor crashed in preview 2 which was already fixed in preview 3.

Preview 3 just can’t connect to the server. I’ve tried setting up a new project, adding the files to a new depot (through P4V), and connecting to it in unreal but to no avail. What surprised me is that the editor remembers my connection information despite me starting a new project. Is there maybe a file in the unreal installation that saves that info, and could that maybe have saved something wrong?

Additional detail: Perforce server is using SSL. Not sure if that matters. The server address ends up being ssl:server.example.com:1666.

EDIT:

Still having this problem on preview 4.
