NodeRed send mail failed

[V_A]

Hello,

I'm trying to send a mail with NodeRed. Some days ago it was already working.

But now I get in the debug window this Error: getaddrinfo EAI_AGAIN smtp.gmail.com

The open Internet connection seams to be okay. I triggered the http request on http://time.jsontest.com and get the actual timestamp.

From my Workstation, I can ping the Mail-Server smtp.gmail.com

So the Server is also working.

For the NodeRed access, I enable the two-factor authentication and create an App-Password in the source Mail-Account, in this case gmail.

I also tied another Mail provider, but still the same Error appears.

Has someone an Idea?

As we are not the provider of the mail node it is hard to help. But in general you problem is caused by network setting problem or missing server functionality. Just search the internet for further information.

Did you do changes to your network/proxy/server settings? Did something change at your internet connection (other provider, new router,...)?
