Hi!
Do anyone came across the below issue while launching Solarwinds Orion web console ?
your requested host couldn't be resolved by DNS.
i think the URL is not resolving from where u are trying to access the console...are u launching it outside of the server?
Try pinging your solarwinds ip from the system command prompt from where you are trying to open your url, if ping is working fine, rather than hostname use your solarwinds ip in link https://(X.X.X.X)/orion rather than https://hostname/orion, if it works from the ip in URL then reach out to your platform team and check if DNS entry for your primary poller in place.
Hope it helps.
