Cannot retrieve license key: SSL connect error

Symptoms

Parallels Plesk Panel version 9.x is running on the server.

The error "SSL connect error" is shown when trying to retrieve the Plesk license key through \{Home -> License Management -> Retrieve Keys\}:

    Key Update Status  
SSL connect error

Also, the following error is generated when trying to connect to port 5224 of Parallels Key Administrator with curl:

~# curl -k https://ka.odin.com:5224
curl: (35) error:1406D0CB:SSL routines:GET_SERVER_HELLO:peer error no cipher
~#

What is causing the problem?

Cause

The problem is caused by libcurl 7.18.2-8 or a newer version of libcurl.

~# dpkg -l | grep curl
ii  curl          7.15.5-1etch1      Get a file from an HTTP, HTTPS, FTP or GOPHE
ii  libcurl3      7.18.2-8           Multi-protocol file transfer library (OpenSS
~#

The connection is correct if specifying version 3 manually:

~# curl -k https://ka.odin.com:5224 --sslv3

The connection fails with version 2, which is used by default:

~# curl -k https://ka.odin.com:5224 -sslv2
curl: (35) error:1406D0CB:SSL routines:GET_SERVER_HELLO:peer error no cipher
~#

Resolution

Please use one of the following workarounds:

  • Downgrade libcurl to version 7.15.5-1etch1.

  • Download and install the new version of sw-cp-server. It can be applied for Debian 5.0 or Suse 11. The appropriate version of sw-cp-server can be found in these attachments:

Debian 5.0 amd64
Debian 5.0 i386
Suse 11.1 x86\_64
SuSe 11.1 i586

If you are using another Linux distribution and downgrading is not suitable for you, please contact the support department .
