Manual pools and RDSH hosts: Agent unreachable

sappomannoz — Wed, 05 Jul 2023 07:42:45 GMT

HI,

last week I had an issue on my on-prem Horizon infrastructure:

Over the course of 2/3 days many agents on Manual VDI Pools and RDSH hosts went into an unreachable state.

Reboot did't help, the only way to re-establish the connectivity was an re-install.

Support couldn't really help, apart: yea some issue, re-install the agents. I'm the only one with this issue?

I suspect that the credentials between the connection servers and the agents where invalidated and the re-install recreates them, but I see nothing obvious in the logs.

Did you try the possibility of restoring the communication between the View Agent and Connection Server via the "reset key" option ? That is our last resort option. Once had to perform it after an upgrade on 4000 vdi`s. On vdi`s where users fiddle with their network adapter also often a solution to get things working again.
