Good Day ,
I did migration from VMware 5.1 to 5.5 with success when I connect with the vSphere web client some time work sometime give me this message :
The connection failed
Firefox can not establish a connection to the server at 10.5.1.8:9443.
The site may be temporarily unavailable or too busy. Please try again later;
If you are unable to load any pages, check the network connection on your computer;
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
can you help me will be thankful.
Regards
You'll need to provide more information than that to get help! What else did you try? Have you ensured the web client service is started? Are you using the vCenter Appliance or Windows version? If the service is started, have you tried looking at log files? To me it sounds like the service may not be running. Have you tried opening a the vsphere web client locally in a web browser on the machine that runs the web client server to rule out firewall and networking issues?
Make sure your DNS is the same as the vcenter server's settings and check your defaut gate etc....sounds more like browser or network
The service is started the problem somtime the vcenter web clinet working sometime no I think is related to the memory ?
Well in that case you should take a look at the log files. Use this KB article to identify the location of your web client service logs:
Then you should troubleshoot if the problem is not immediately obvious from looking at log files. Use this KB article to help troubleshoot:
Hope that helps!
