I migrated librenms to another VM yesterday and thought everything was working correctly. The devices are polling correctly.

However, if I click on any device listed in the librenms webui I get an error “Whoops, looks like something went wrong. Check your librenms.log.” Looking at the log I see the following with every attempt to open a device.

I found another thread where if you have your domain defined as an array it could cause this but I’m not sure where to look for this setting. Other than that, I’m not sure what else to check to resolve this issue. Any help would be greatly appreciated.
