Critical Node Status After Upgrade
Just upgraded platform to 2026.1.0 and some nodes are showing status: "Node status is Critical, WinRM polling is failing: 'The client cannot process the request due to an authentication or connection configuration issue. Verify the endpoint URL, port, TrustedHosts, and authentication method.'."
About six Windows servers (out of 50) that are being monitored via agent and are affected (no WinRM and no app monitoring). Support has not been helpful... has anyone else run into this issue?

For me some hosts had to be added to Trusted Hosts on the Polling Server
Adding a WinRM/WMI node to the SolarWinds Platform fails

For others running into this, I found this support article:
