UMC-Server: broken SSL communication after joining DC Slave/Backup
Last modified: 2015-08-27 18:13:18 CEST
Nothing possible anymore with UMC after a DC Slave joined (successfully but with Bug #38051. 16.03.15 15:33:03.599 SSL ( WARN ) : SSL error in _receive: (-1, 'Unexpected EOF'). Probably the socket was closed by the client. 16.03.15 15:33:03.599 MAIN ( PROCESS ) : Processor: dying 16.03.15 15:33:41.083 SSL ( WARN ) : SSL error in _receive: [('SSL routines', 'SSL3_READ_BYTES', 'tlsv1 alert unknown ca'), ('SSL routines', 'SSL3_READ_BYTES', 'ssl handshake failure')]. Probably the socket was closed by the client. 16.03.15 15:33:41.084 SSL ( WARN ) : SSL error in _receive: [('SSL routines', 'SSL23_GET_CLIENT_HELLO', 'unknown protocol')]. Probably the socket was closed by the client. 16.03.15 15:33:41.083 MAIN ( PROCESS ) : Client: Setting up SSL configuration failed: [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')] 16.03.15 15:33:41.083 MAIN ( PROCESS ) : Client: Communication will not be encrypted! 16.03.15 15:33:41.085 MAIN ( WARN ) : Client: _recv: error on socket: [Errno 104] Connection reset by peer
Happened again to me. I joined a DC backup via UMC. It went successful. I did not restart UMC. Login is impossible without any error message. UMC shows only the gray background.
