ESXi 7 U3 - 503 error on Web interface

[Claudiuz89]

Hi, an our customer using VmWare ESXi 7.0 Update 3 is facing some serious problems.
A lot of times a day when logging-in via web console receive a 503 Service Unavaiable.

The complete text is:

503 Service Unavaiable (Failed to connecto to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x0000006d3a827900]_serverNamespace = / ation = Allow _port = 8309)

If i login via SSH to ESXi and i launch services.sh restart, all works great again but in a few hours we receive the same error and we need to launch another services.sh restart.

Witch this problem, the Nakivo backup can't discover VMWare host and so backups don't work

Has someone experience on this?

Thanks
