B4J Question [SOLVED] [WebApp] SMTP working in debug but not on release

[ziovec]

Hello there!
I noticed that during debug and local testing I'm able to send emails with smtp.
I tried just now with the release jar file over a VPS and everything is workin, except the smtp stuff.

Code snippet:

Sub SendInfoMail  
    SMTP.Initialize(Main.settings.Get("smtp"), Main.settings.Get("port"), Main.settings.Get("account"), Main.settings.Get("pwd"), "SMTP")
    SMTP.UseSSL = True
    SMTP.To.Add(Main.settings.Get("infomail"))
    SMTP.Subject = $"WEBAPP - Nuovo ordine da ${ws.Session.GetAttribute("username")}"$
    SMTP.Sender.Replace(SMTP.Sender, "WEBAPP PELISSA")
    SMTP.HtmlBody = True
    SMTP.Body = $"Nuovo ordine inoltrato da <b>${ws.Session.GetAttribute("username")}</b><br>
    spedito il ${giorno} alle ${ora}<br><br>
    In allegato copia PDF come spedita al cliente.
    <br><br><br>
    Si prega di intervenire su VERDE per la corretta acquisizione del documento."$
    SMTP.AddAttachment(File.DirApp, $"${documentName}.pdf"$)
    SMTP.Send

    Sleep(100000)
    File.Delete(File.DirApp, $"${documentName}.pdf"$)
   
End Sub

Main.settings is a text files that contains all the parameters for the email adress.
I would like to underline again that this code works in debug, but seems to not work aftere release
Am I missing something?

Where is the full errormessage?

Now I'm afraid to look dumb...how do I get all the console log running a jar file under windows server?

Dumbness solved.
Here's the error:

Looks like an auth error...but how?

In my settings file I'm using
smtp=smtp.gmail.com
port=465
Already checked in google account settings for third party allow.
Already tried port 587, getting a slightly different error about SSL (I guess it's because it's not the righ port)

As I said, with the same exact configuration everything works fine in debug mode

You are surely moving the application to your server In a new location than the development areas. What I did is to create a gmail account from the server location. And use it only there.

Doesn't make sense to me.

Gmail should work regardless the platform if user and password are given correctly.

Yes theoretically. When you change your location or even phone or computer they seem to create an authentication issue. I'm talking out of experience. Try creating a Gmail test account on server and see the results.

1. Remove the Sleep.
2. Handle the MessageSent event ( [B4X] Net library (FTP, SMTP, POP) with Wait For )

I assume that it is a WebSocket handler.

Yes, it is.
Thanks for the hint, already changed the sleep into waitfor...I didn't remember it ^^

@jahswant you were right!
I tried logging into Gmail from the server and from that moment SMTP started working...good to know for the future!
