SMTP Error: Could not authenticate

Support
1

Hi

I’ve installed InvoicePlane on Wamp server,
I was testing all the function.

When it came to the email part,
I was able to send mail twice using
my SMTP method

but the 3rd time its showing
the error SMTP Error: Could not authenticate

How can I resolve this, Thanks

Hi,

This probably is caused because of wrong smtp settings. Did you check the correct port that should be used according to your mail service provider? The default one is 587 in most cases.

Could not authenticate means in most cases that your credentials are not correct.

Also make sure that you are allowed to use that mail server from your local ip adresse.

Regards,
Niels
