Hi, I'm getting a "send failed" and the following error when trying to send an email with the email node (node-red-node-email). Error: connect ENETUNREACH 2a00:1450:400c:c00::6c:465 - Local (:::0) at internalConnect (node:net:1010:16) at defaultTriggerAsyncIdScope (node:internal/async_hooks:464:…

It appears to be trying to use IPv6 to connect to the server. What have put for the email server address in the email node? Also what do you see if you run ping server_name where server_name is whatever you have put as the server in the email node.

I'm sending via gmail. Server: smtp.gmail.com Port: 465 Use secure connection: ticked PING smtp.gmail.com (108.177.15.109): 56 data bytes 64 bytes from 108.177.15.109: icmp_seq=0 ttl=101 time=32.528 ms 64 bytes from 108.177.15.109: icmp_seq=1 ttl=101 time=32.377 ms 64 bytes from 108.177.15.10…

How did you install node red? Is it a docker install for example? Are you absolutely certain this is coming from the email node? What do these commands give? ip addr dig smtp.gmail.com ping6 smtp.gmail.com

The Error comes from the email node. But the root cause is probably something else, potentially IPv6 related. I'm quite new to this so no experience in debugging at this level. I used this script to install Node Red bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master…

I have ZeroTier (an IoT VPN) installed, the info under 4. comes probably from there. Possibly it is the culprit? I only have wifi and I've de-connected and reconnected to the wifi, no change. I've added IPv6 Auto-Assign on ZeroTier and rebooted the Pi, no change.

First I want to thank you for the time spent on this persisting error! I've deleted Zerotier from the Raspberry, but still same error on the email node ... ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:0…

It is very strange. I can only suggest disabling IPv6 completely in the pi.

We do seem to have suddenly started seeing this a bit - eg see this thread - Sending email : "Error can not use ipv4 addresses with current network" - no-one has totally pinned it down yet.
