    Hi, as a first step, can you clear the configuration cache and check again ?

  1. Go to Central Administration->Application Management->Manage services on server->select your search server in Server section located in the top-right corner. Check if there is Distributed cache service, if so, stop it.

  2. Try to increase the timeout for the LMTCache and DistributedActivityFeedCache using PowerShell command below:

$lmtcache = Get-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedLMTCache

$lmtcache.RequestTimeout="10000" Set-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedLMTCache $lmtcache

$feedcache = get-SPDistributedCacheClientSetting -containertype DistributedActivityFeedCache


Set-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedCache $feedcache

Then use the following command to populate the cache quickly:

Update-SPRepopulateMicroblogLMTCache -ProfileServiceApplicationProxy <SPServiceApplicationProxyPipeBind> [-AssignmentCollection <SPAssignmentCollection>]

Update-SPRepopulateMicroblogFeedCache -[AccountName <AccountName>] -ProfileServiceApplicationProxy <SPServiceApplicationProxyPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-SiteSubscription <SPSiteSubscriptionPipeBind>]-[SiteUrl <SiteURL>]

this type of error occurred when one of the server is unable to decrypt the Key associated with farm.

This key has two pairs, one stored in the registry (after you add a SharePoint server to the farm) while the other piece is stored in the Config db. more details here:

If possible to remove the server from farm and re add it and see it that fix the issue.

  • I did that i remover server and joined again in farm
