Recently I have observed several instances of where ESXi credentials have suddenly become bad, for no apparent reason.
This is true, from both a Web browser, and while attempting to use an ssh shell.
On some occasions, this appears to be temporary, and I can login with no intervention.
Other times, I had to login to the ESXi locally, by attaching a monitor and keyboard to the local machine.
With the local attachment, the password was good.
After I reboot the machine, then I can reach the ESXi machine through either browser or ssh command prompt as usual.:
Question: Am I describing a known problem, and if so if there a fix for it yet. If not, what information do I need to collect to open a problem.
From: slptool the product level is: product="VMware ESXi 6.5.0 build-6765664"
