Help with Debuggin SMTP email connection issue

cowsoncomputers

I am new to Flarum - am excited to be moving my forum after many years running Vanilla.

I have run into an issue with setting up email. Hosting is Linode VPS, php 8.3, installed using composer. version 1.89

I setup email using smtp with Mailgun, port 587, encryption as TLS. Tested port to confirm it is open. The test email DOES get sent and I receive it BUT I always get an error message, whether sending a test email on the email settings page or on the front end, logged in or not. There are no errors in the error log file.

I considered using the Mailgun option but when trying to install Guzzle, I get this conflict:

Why might I be getting this conflict?

Any assistance in how I might get either SMTP or Mailgun settings to work without error displaying would be greatly appreciated!

cowsoncomputers is this a new linode vps? Outgoing mail ports are usually blocked with providers like these.

And what error do you get when test sending?

The output of php flarum info would be good to have as well.

It is not a new Linode, have been with them for many years. The port is not blocked:

I get the red-background "Oops Something went wrong. Please reload the page and try again." message in all cases.

Here is the flarum info:

cowsoncomputers check storage/logs for the error. See https://docs.flarum.org/troubleshoot

The important issue here seems to be that the email DOES get sent but not without a fatal error:

Has anyone else seen such an error?
