Our qlik sense server is getting unresponsive over the time and we are trying to figure this out as what is causing this issue.
I can see few stack trace in my qlik sense log file and want to decode and understand them. It will be great If anyone can help me understand this.
Unanticipated System.Security.Authentication.AuthenticationException occurred accepting client, disposing connection attemp.The client and server cannot communicate, because they do not possess a common algorithm.A call to SSPI failed, see inner exception. at System.Net.Security.SslState.EndProcessAuthentication(IAsyncResult result)?? at Qlik.Sense.Communication.Communication.Tcp.StreamFactory.<>c__DisplayClasse.<>c__DisplayClass10.<Negotiate>b__c(IAsyncResult result)
Error when committing Exception of type 'Qlik.Sense.Common.Exceptions.ConflictException' was thrown at Repository.Core.Repository.Common.AbstractModelRepository.CheckConflicts(IRepositoryObject persistedItem, DateTime itemModifiedDate) at Repository.Core.Repository.Common.ModelRepository`1.Update(T item, Boolean appendPrivileges, Int64 privilegesFilter) at Repository.Core.Repository.Common.TransactionUtility.RunInTransaction(ITransaction transaction, IEnumerable`1 actions)
I also get this SSPI error logged to "C:\ProgramData\Qlik\Sense\Log\Proxy\System\OMQSDEV01_Service_Proxy.txt" every 1 minute. I can't see any immediate issues - my servers works - but it's concerning it's logging this error all the time.
