IssueWhen browsing the to MapR UI in certain versions of Chrome, the user is blocked with the following error message:

ERR_SSL_VERSION_OR_CIPHER_MISMATCH


 
CauseRecent versions of Safari and Chrome web browsers have removed support for older certificate cipher algorithms, including those used by some versions of MapR. Because of this, users of these new browser versions may lose the ability to log into MapR Control System (MCS).
ResolutionTo resolve the issue, follow the steps provided by MapR when a browser is unable to establish a secure connection.



 
WorkaroundYou may receive the following error when running the fixssl script:  

No webserver found on node.  No changes made


If this occurs, issue the following commands:

# /opt/mapr/server/manageSSLKeys.sh create -N saw -ug mapr:mapr
# /opt/mapr/adminuiapp/webserver restart
