admin console - RemoteManager error email queue page
I am receiving an error on the admin page which displays queues. Daily statistics say I have an email stuck somewhere. Number of mails is more than I sent on my personal zimbra server.
Release 8.6.0.GA.1153.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.6.0_P2.
Remotemanager: server --> server:port} error:service.FAILURE Method: [unknown] Details:soap:Receiver
* change SSH port from 22 to correct port -- no solution (eg. zmprov ms zimbra.domain.com zimbraRemoteManagementPort 1000)
* new certificates - no solution (zmupdateauthkeys and zmsshkeygen)
* firewall disable - no solution
Both client pc and server resolve the hostname of the server. SSH is working from client pc.
Testing with ssh -vi .ssh/zimbra_identity -o strictHostKeyChecking=no email@example.com -p 22 (correct name and port to me) asks for a password....
worked through article: http://wiki.zimbra.com/index.php?title=Mail_Queue_Monitoring
Can't find if this is a fixperms issue.
