Troubleshooting Tip: Revoked certificate prevent Admin UI access

Most browsers will refuse to open the Admin UI page if the web service certificate has been revoked. To resolve this issue, it is required to reset the web service certificate to a self‑signed certificate and then upload the new valid certificate through Admin UI.

1. Delete the revoked certificate:

keytool -delete -alias tomcat -keystore /bsc/campusMgr/.keystore -storepass ^8Bradford%23

2. Generate a new certificate:

keytool -genkey -alias tomcat -keyalg RSA -keysize 2048 -validity 3650 -dname 'CN=bradfordnetworks.com,OU=Bradford Networks,O=bni,L=Concord,ST=NH,C=US' -keypass ^8Bradford%23 -keystore /bsc/campusMgr/.keystore -storepass ^8Bradford%23

3. After login, upload the new certificate from Admin UI in System -> Certificate Management -> Admin UI. After the service is restarted, the new certificate should be applied. The same certificate can also be copied to the Persistent Agent and the Portal service.
