Problem

-- getting this error when trying to connect to Integration System Manager "SSL client handshake error"

Resolution

* look at Integrator/data/log/starter.log and look for this error :

'SSL verify error in certificate, not valid after .....'.

* open -> Configure UI Connection -> Personal certificates and check the validity date

* if the certificate is expired, generate a new valid personal certificate and make it as default

* if present, remove the line "<server>/<port=<fingerprint>" after [SHA-512_Fingerprints] from tsclient.ini

* restart B2Bi
