• Any errors that appear in your browser's error console.: None

• Confirm whether the error is reproducible on the demo: https://snipeitapp.com/demo.: Pre-Flight not on demo

• Include any additional information you can find in storage/logs and your webserver's logs.: laravel.log file contains same data as above

• Include what you've done so far in the installation, and if you got any error messages along the way.: Initially, I was unable to get the Pre-Flight page to load. Through researching online, I ran the following command which solved the permission issues:
  chmod -R 777 snipeit

• Indicate whether or not you've manually edited any data directly in the database: Have not done any manual editing

6.18.10 is your Laravel version. What Snipe-IT version? How does the .env look?

6.18.10 is your Laravel version. What Snipe-IT version? How does the .env look?

I installed SnipeIT via GIT a few weeks ago. I am unsure how to determine the version that was installed.
Regarding the .env file, I'm assuming you're interested in the Outgoing Mail Server Settings:
# --------------------------------------------
# REQUIRED: OUTGOING MAIL SERVER SETTINGS
# --------------------------------------------
MAIL_DRIVER=smtp
MAIL_PORT=25
MAIL_USERNAME=░░@░░░░░░░░░.com
MAIL_PASSWORD=░░░░░░░░░░░░
MAIL_ENCRYPTION=null
MAIL_FROM_ADDR=░░@░░░░░░░░░.com
MAIL_FROM_NAME='Snipe-IT'
MAIL_REPLYTO_ADDR=do-not-reply@░░░░░░░░░.com
MAIL_REPLYTO_NAME='DoNotReply'
[email protected]

I've also tried these, but same results:
MAIL_PORT=587
MAIL_ENCRYPTION=TLS

[Relix360]

@pabs2112 you dont have the MAIL_HOST= variable on the .env?

[pabs2112]

@pabs2112 you dont have the MAIL_HOST= variable on the .env?

Oops... It does have it... I just forgot to post it:
MAIL_HOST=░░░.░░░░.com

Also, in the Laravel console, after running the test, 2 Messages and 3 Exceptions. For each of these includes a stacktrace. It would be a lengthy post to include everything. I can provide all if it would help.

Also, in the Laravel console

Laravel console? Not sure what you mean.

For each of these includes a stacktrace. It would be a lengthy post to include everything. I can provide all if it would help.

Yes please. I can't really tell what's happening here.

I read another posted Issue #8448 about testing from within the settings menu. I just ran that test... It failed again but now has different errors. There are 2 error messages, and 1 exception report:

Actually, because the above errors have to do with TLS, I tried disabling TLS within the .env and I was able to get a successful test email message sent. So it's working now.
The original failure during the preflight test remain a mystery, because I tried with and without TLS and it had no effect. The original errors were speaking of something to the effect of it being unable to include images. I have no idea. But, I am ecstatic that it's finally working now.

Earlier versions would have failed on the preflight was because there is not yet a settings record and we were attempting to call properties on a record that didn't exist.

Glad to hear you're all set now.

The version I installed was v5.0.4 - build 5452... That's only a few weeks old. Was this already corrected in the current builds?

[snipe]

We're already up to v5.0.6 - that issue was fixed in the past few days
