On a client of mine, I enabled the SSL on the Domino Server, by doing the steps in the Help File.
The first time I launch HTTP ask after that it works fine.
After I restart the HTTP task, I always receive the above error, and I loose access to the server via Web Browser.
I've tried several things, including recreating the certificate, changing the permissions on the files keyfile.kyr and the associated pair (as mentioned in some posts) and nothing works.
For now, I keep the access to the server with SSL disabled.
The environment is:
Lotus Domino Server 6.5.3
Windows XP Professional
