Newsfeeds do not roll up and receive errors:
SharePoint returned the following error: The operation failed because the server could not access the distributed cache. Internal type name: Microsoft.Office.Server.Microfeed.MicrofeedException. Internal error code: 55. Contact your system administrator for help in resolving this problem.
Fist run the following to rebuild the Distributed Cache and then add the user profile app pool account to the User Profile Service Application Permissions:
#
# Command used to determine if the cache is running.
Use-CacheCluster
Get-CacheHost
# rebuild Distributed Cache
Remove-SPDistributedCacheServiceInstance
$SPFarm = Get-SPFarm
$cacheClusterName = "SPDistributedCacheCluster_" + $SPFarm.Id.ToString()
$cacheClusterManager = [Microsoft.SharePoint.DistributedCaching.Utilities.SPDistributedCacheClusterInfoManager]::Local
$cacheClusterInfo = $cacheClusterManager.GetSPDistributedCacheClusterInfo($cacheClusterName);
$instanceName ="SPDistributedCacheService Name=AppFabricCachingService"
$serviceInstance = Get-SPServiceInstance | ? {($_.Service.Tostring()) -eq $instanceName -and ($_.Server.Name) -eq $env:computername}
$serviceInstance.Delete()
Add-SPDistributedCacheServiceInstance
Get-CacheHost
# confirm that UP is reported
#add USP application pool to USP
#first run Get-SPServiceApplication to find the USP ID
$account = New-SPClaimsPrincipal -IdentityType WindowsSamAccountName
$UPA = Get-SPServiceApplication
$sec = Get-SPServiceApplicationSecurity $UPA
Grant-SPObjectSecurity $sec -Principal $account -Rights "Full Control"
Set-SPServiceApplicationSecurity -Identity $UPA -ObjectSecurity $sec
Wondering if you have seen a different Newsfeed error in SP 2013 (on Prem, not online). Newsfeeds seem to work fine in MySites, but in a Site Collection set up for Project sites with site feed enabled at root and subsites, when you try to post “We’ve hit a snag
Looks like the newsfeed was removed from the site, the site was deleted, or there’s some temporary network problem. You can try again later or stop following the site from the sites page.”
Have tried de-activating and re-activating site feed, increasing size of Distributed Cache. Can’t seem to find anything online about this. Thank you.
