is the error object? How can I resolve this error condition on VMware ESXi? (I'd post the version number but I don't know how to get it without the vSphere console!) error 503 backend fetch failed backend fetch failed guru meditation EDIT: Roughly a month after I asked this question, the server inexplicably rebooted itself. error 503 backend is unhealthy I don't know if it panicked or what happened… but after it rebooted, this problem was gone. So I can't test / error 503 guru meditation confirm any of the answer unless the problem reappears (which I hope it does not! however to provide myself a workaround best weblog is errorwebsites and best web site is sanarena com I would simply restart https://www.reddit.com/r/techsupport/comments/3jhn0u/no_healthy_backends_error_when_i_visit_the_python/ vmware server service and then I could log in no problem and access vm consoles. After 5 minutes or so the consoles would go black and I could no longer access them. If I logged out and tried to go back into vcenter I would get this error: Call "ServiceInstance.RetrieveContent" for object "ServiceInstance" on Server "my.host.name" failed. So the rule is if you can get into vcenter go check the EVENT logs https://errorwebsites.wordpress.com/2013/08/17/what-is-error-what-is-error-503-what-is-the-error-object-how-can-i-resolve-this-error-condition-on-vmware-esxi/ and see if there are any access denied alerts.

[ author ] Thanks robert, But i have already tried all this stuff's. The problem with probing is that if your back-end is unhealthy for a second and if varnish declares it unhealthy due to some reason than it shows backend unhealthy for next 5 mins or so whereas the interval is only 5s. So if i m running on one back-end all the requests for this backend fails. The one i m using is a very domain with 3000 req/s. so cannot afford a second of unhealthy network or unreachability.
