ok sorry for the time taken to reply- here is the latest. I created a DNS record for broker.xxx.com verified that it's working and verified that port 8883 is open on the host. Netclient seems to be working fine, but still won't connect. here's the latest Netclient pull- [netclient] 2022-05-18 11:47:20 initializing network test [netclient] 2022-05-18 11:47:21 started daemon for server broker.wg.domain.com.au [netclient] 2022-05-18 11:47:21 netclient daemon started for server: broker.wg.domain.com.au [netclient] 2022-05-18 11:47:52 unable to connect to broker, retrying ...

I'll have a look at the logs there
