Mail: No notification settings found

[paul-eff]

Hi there,

I just setup the Nutify Docker container and got everything up and running and connected.
Now I wanted to configure mailing for the case something goes wrong, and I ran into the problem where the test mail (when configuring the mail connector) and reports work, but I get a strange error when trying to send a test mail from the Notify tab (Mail: No notification settings found).

Nutify sits behind a Nginx Proxy Manager reverse proxy, sockets and HTTPS are enabled, traffic is routed to NPM via a AdguardHome DNS Server. Everything is on the same RasPi4 and working fine for the rest of my homelab.
I'm hoping it's just the 1:45AM time and I am overlooking something very obvious.

Cheers and thanks!

Environment: RaspiPi4 (RaspiOS Lite 64-bit, Debian 13 trixie)+ Docker (v29.3.1, build c2be9cc) + dartsteven/nutify:latest-raspberrypi5-arm64 (v0.2.0)

Profile: Single

Topology: 1 Server, 1 UPS, connected by USB-B to USB-A cable

Symptom: Not sending (test and real) mails on system events (UPS on Line Power, Low Battery, ...). Logs are fine and events do register normally

Expected: Receive a test or real mail im case of event. For any other service provided by Nutify, which provides a report via mail, everything works as expected.

When started: From beginning :D

Recent changes: nothing, fresh/first install ever

Please, try this

docker pull dartsteven/nutify-internal-testing:0.2.1-amd64
docker pull dartsteven/nutify-internal-testing:0.2.1-raspberrypi5-arm64
docker pull dartsteven/nutify-internal-testing:0.2.1-raspberrypi4-armv7
docker pull dartsteven/nutify-internal-testing:0.2.1-mac-arm64

Hi @DartSteven ,
nutify-internal-testing:0.2.1-raspberrypi5-arm64 fixed the general problems I had with the notifications (live and when pressing the test button).
Now I have the weird bug (maybe?) where if I e.g. send a testing mail for "UPS on Battery", I also get a notification for "connection lost" and "reconnected" (so 3 in total). Also happens when I e.g. disconnect the USB cable from my RasPi to the UPS.
There is a minimal chance that maybe older messages where queued up from me mashing the test mail button yesterday. But it was weirdly only happening when sending a new test mail.

Cheers and thanks for the fast fixes!

Could you please start from a completely clean environment, using an empty directory with no database and no existing files, just to rule out any doubt on my side?

If it still keeps sending 3 notifications, could you also attach the logs for me?

[paul-eff]

Sure no problem.
I'll get to it tomorrow, but I unfortunately won't get to it today anymore.
Cheers!

Hi @DartSteven ,
deleting all files in the Docker binds did the trick, all is configurable now, testing mails works as expected.

I then did a production test and just disconnected the USB cable between the RasPi and UPS and then I received 3 mail.

Is this intended? I would expect to also receive a "UPS reachable again" mail.

Cheers and thanks for the help.

Please, I have created the 0.2.2 build.

Try one of these images and let me know if it fixes the issues you were experiencing. If the problem persists, please let me know so I can investigate further.

Hi @DartSteven

I'll take a look at it tonight.
Thanks for your efforts.

Cheers

Hi @DartSteven ,
I tried version nutify-internal-testing:0.2.2-raspberrypi5-arm64 and experienced the same behaviour as lastly reported for nutify-internal-testing:0.2.1-raspberrypi5-arm64.
Mail sending etc. all works perfectly fine but I again experienced the case that I got a COMM LOST and UPS UNREACHABLE but only a COMM RESTORED mail.

Everything else seems to work as intended.
Cheers!
