TerraMaster Forum

I've had a F4-424 Max for a little over a week and for the life of me, I can't get it connect to my UPS server. Other clients work perfectly but not this one.
I've checked the nut.conf and upsmon.conf files many times and they are correct but it appears the NAS is trying to connect to something other than what's in the upsmon.conf file.

it should be <myups@ip_address> so it looks like I'm missing something.
Any suggestions?

Please tell me the TOS version.
The recently released 6.0.794 has modifications for UPS. If you are still using an earlier TOS 6 version, please update and try again.

yes, that is the version I'm using.

on the TNAS, when I run 'upsc myups@ip_address', I get all the info from the UPS so I'm not sure why the Enable UPS on the TNAS keeps failing

OK...thanks

We found that the UPS name on the server is not 'ups'. Please check the server. It is simultaneously connected to UPS names 'myups' and 'ups'.

It seems you are using a custom UPS service. If that is the case, please do not use TOS's UPS front-end page. After completing the direct configuration, please restart nut-monitor in the Terminal.

there is no problem with the server. 2 other clients connect to it.
how do I stop the Terramaster attempting to connect to 'ups'? It should only connect to 'myups'

Modify the /etc/nut/upsmon.conf
Change "[email protected]" to "[email protected]",
Then restart the service.
systemctl restart nut-monitor.service

This remains a problem. I just had a power failure while I was asleep. When I woke up and realised, I saw that the F4-424 Max was powered off.
The upsmon.conf file has no reference to "[email protected]" It is as it should be.
