404 when trying to access Plesk control panel after upgrade to 10.3.1

[ShaneWealti]

I recently tried to upgrade to 10.3.1 using the interface for doing upgrades in the Plesk control panel. After it finished, I was (and still am) no longer able to access the Plesk control panel. It gives me a 404 error. I'm on a dedicated server. CentOS 5 (64 -bit) - hosted by 1and1.

Any ideas on how I can troubleshoot this?

Check error messages in /var/log/sw-cp-server/error_log at least.

Looks like something to do with SSL

The /var/log/sw-cp-server/ log has three entries all the same:

2011-09-04 20:19:50: (connections.c.299) SSL: 1 error:140940E5:SSL routines:SSL3
_READ_BYTES:ssl handshake failure

So it looks like some kind of problem with SSL. I didn't make any changes relating to SSL. Is there a way I can disable SSL and just use a plain http connection temporarily so that I can get into my control panel and check some settings.
