SMTP Error: Client network socket disconnected before secure TLS connection was established

[PeterXQChen]

Trying to setup Email SMTP notification but keep getting this error when testing.

I've used the same setting for other services and they work fine.

Tried playing around with the settings and changing ports and what not. Nothing works.

Can't find related issues.

I suggest you could check/uncheck the "Secure".

Yes i've tried that setting, nothing works.

Found a possible reason, the smtp's TLS probably too old and Node.js no longer supports it.

If you installed the Uptime Kuma via Docker, I built-in Apprise, which also supports SMTP and it is based on Pyhton, it maybe works:

Thanks! I'll give Apprise a try.
