    Sbarnet: Thank you for sharing the logs. Unfortunately there isn't enough information to debug the disconnects. I recommend to open a support case and provide activity IDs for the connections you see issues with.

Yesterday, 9/3/2020 was pretty bad.  We have a small shop client that we setup with WVD Spring Release back in May, and they have had instances like this where they all get disconnected at the same time.  

 

According to Log Analytics, these are the reasons for failures

 

CodeSymbolicUserCount
NL_ERR_TDSKTCONNECTFAILED24
ConnectionFailedClientDisconnect24
UnexpectedNetworkDisconnect17
ConnectionFailedServerDisconnect6
CM_ERR_MISSED_HEARTBEAT6
SavedCredentialsNotAllowed4
NL_ERR_TDTIMEOUT4
SSL_ERR_FRESH_CRED_REQUIRED_BY_SERVER4
ConnectionFailedUserHasValidSessionButRdshIsUnhealthy2
ConnectionFailedRDAgentBrokerConnectionNotFound1

 

These disconnects happened pretty much all throughout the day, makes it extremely frustrating and hard for them to do their work, and frustrating for us trying to provide a root cause analysis.  Overall WVD is great, as long as it's working properly and the users are not getting disconnected.  Hoping that someone can weigh in on some insight as to what might have been happening yesterday.  I can provide more details if someone from Microsoft WVD support would like to review the correlation event IDs from the logs gathered from Log Workspace.
