Also , when I used the article as described to lengthen vcenter server timeout , when I edit and choose timeout settings , it just sits there with Loading..... forever.
Any idea on this issue?
This could be an known issue. This issue will be similar to this KB described. Cannot access the vCenter Server Advanced Settings panel in the vSphere Web Client (2064058)
Could you please upload vc-support logs, VI Client, Web client logs at the time of issue occurs.
