Security

Dear Team,

We have ClearPass 6.8.7 version and more than 10 ClearPass servers in the clusters. Due to network issue 4 of our servers have gone out of sync and are no more part of the cluster. We dropped these subscribers and tried to add them again in the cluster but we are getting an error message, "Exchanging CA certificates failed".
We tried adding DB, HTTPS certs from publisher to affected subscriber nodes but nothing helped. Could you please help and assist in this matter. Please provide any fix or solution

Hi Muhammed,

I would recommend you to open an Aruba Support ticket to support you on this kind of issues. You could take a look in the event viewer if there is some more information why the error occur.
