Thank you Sergey How am I supposed to delete the secondary storage with running System VMs? It gives this Error : Cannot delete image store with active templates backup!

Re: Web Console Timing Out
The error is right here in the log. SSVM is supposed to have secondary storage mounted over NFS. 255.255.255.0 is not the correct IP. Likely, the cause is garbled record for secondary storage. Try to delete it and re-add.
