After upgrading from BE 2014 to BE 15 (actually it was uninstall BE2014 and install BE 15) I cannot access a vSphere 5.5 Server.
If I try to backup , then i get a failure message saying that the credentials could not be tested, sometimes "server did not answer". Changing credientials does not help.
Also I cannot open the tree of VMs as before. The message says simply "a communication failure occurred". therefore I cannot build a new backup job
i already read something about this phenomen, but this seemed to work for already existing jobs with failure meesages logged.
I tried to replace the actual libcurl.dll by a version from BE 2014 - no change. i also de-activated IPv6 on the backup server - no change.
All updates are installed.
Agent seeems to be working
Can someone help me ?
