[ovirt-users] Really weird ! Image IO / browser upload only working on 1 cluster (out of many) - anyone got any advice ? (network access, certs seem fine.)

One for the mystery van .. I am running OLVM/ Ovirt 4.5 (engine) - hosts presently mised 4.4.x and 4.5.x - however version doesn't seen to be the issue We have muliple DC's/Clusters each cluster has 2 hosts and then have access to different fc SAN volumes - each san vol is a sperate storaqe domain I,e host 1 + host 2 --> San 1 host 3 + host 4 --> San 2 , etc SAN connection for the hosts/clusters generally is working fine and I can also upload to any SAN volume using the upload script - /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py However imageio via browser ... We have a major issue. I am not able to upload (via browser) any files to any storage domain apart from 1... (say San 1) Yes, I have imported the CA to browser, and All storage domains pass the 'test connection' -> "Connection to ovirt-imageio was successful." However I can see what the issue is (but not why there is this issue..) In the upload image section of all domains the available host to use (to piggyback connection) as the same - host 1 + host 2 But those hosts only have access to one SAN not all of them i.e for San 2 I should be able to choose host 3 + 4 ... (but only host 1/2 are showning in all domains..) If I use the upload script it uses correct host and successfully upload - but not via browser.. I have checked and /etc/ovirt-imageio/conf.d/60-vdsm.conf is the same for ALL hosts. Certs seem ok all a I can telnet to all hosts from engine on port 54322 Can anyone give me any ideas how to troubleshoot this ? Thanks
