Error setting up email

AndyS

I am getting an error message when sending a test mail after setting up email configuration

Email configuration

Host: smtp.gmail.com
Port: 587
Encryption: ssl
Username: myaccount@gmail.com
Password: my google password

Error in log:

flarum.ERROR: Swift_TransportException: Connection could not be established with host smtp.gmail.com :stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:
error:0A00010B:SSL routines::wrong version number in /home/[masked]/public_html/flarum/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:261

Flarum installation details:

Flarum 1.8.5
PHP 8.2.21
MySQL 10.6.18-MariaDB-cll-lve

Can anybody suggest what I need to do/investigate to fix this?

AndyS your hosting provider is probably blocking the outgoing email port to prevent spam runs. Check their faq or contact their support.

luceos Thanks for the advice. I'll check that out

I solved it. I had configured port 587 which is for TLS in gmail. I changed it to 465 (for SSL) and the connection was attempted but failed. It turns out I also needed to generate an application-specific password in my gMail account for my forum. After pasting that password into the email configuration I successfully sent a test email.
