MS SSAS named instance doesn't work after NTLM deny

Named instance MS SSAS don't accept connections after NTLM incoming/outgoing traffic deny. There is SPN for this server like: FQDN SPN: Setspn -s MSOLAPSvc.3/AW-SRV01.AdventureWorks.com:AW-FINANCE AdventureWorks\SSAS-Service NetBIOS SPN: Setspn -s MSOLAPSvc.3/AW-SRV01:AW-FINANCE AdventureWorks\SSAS-Service Also default instance on the same server works correct without any problems. SPN was added same way: Setspn -s MSOLAPSvc.3/AW-SRV01.AdventureWorks.com AdventureWorks\SSAS-Service
