Network issue

[timowevel1]

Hello,

I tried to set it up on a fresh installed Ubuntu 20.04 Server. I ran the install script and there I already got errors like that /var/www/vendor could not be created and many Permission denied's. Of course I ran it as root and with sudo.

When I start the webinterface I can access it, but when I try to Sign Up I get a "Network error".

Did anyone experience this?

[timowevel1]

And of course thank you for this amazing project! It is really nice but because of the problem above I cant use it.

That is probably because your server (nginx/apache) is using the www-data user.
I'd advice you to change the owner&group of your application directory to www-data (or whatever your webserver uses), eg: chown -R www-data:www-data ./your_presentator_dir/ OR to add www-data to your user group.

In general you should avoid using root when executing console commands since that most likely will mess up your file permissions.

I'll close the issue since it doesn't seem to be a bug with Presentator, but please comment if you are still experiencing further issues.

Thank you. I noticed that this one was not for production. Now I installed it with the production guide and I'm experiencing errors when logging in. Database and everything is setup. Could you tell how to install the php extension "reflection" and the rest? System is ubuntu. It drops me an Internal Server Error 500 everytime, maybe its php.

/api/users/register:1 Failed to load resource: the server responded with a status of 500 (Internal Server Error) /api/users/register:1

The php socket is also setup correctly in the nginx conf (Php7.4-fpm.sock). File is also on the specified location, probably php extensions are missing.

@timololipop Ubuntu usually follows this patternsudo apt-get install php-... or sudo apt-get install php7.4-.... Just google "ubuntu php install ..." and you should be fine.

Although I haven't tested it with the production setup, you should also be able to run manually the requirements check by executing
php /path/to/your_presentator/vendor/presentator/api/requirements.php

Please provide detailed log if the above error persist (and if possible, your nginx config).

The path to yii framework seems to be incorrect. You need to install Yii framework via composer or adjust the framework path in file requirements.php. Please refer to the README on how to install Yii.

[timowevel1]

But on composer install it tells me:
`> @php yii healthcheck/db
DB connection is established.

@php yii migrate/up --interactive=0
Yii Migration Tool (based on Yii v2.0.40)
`

[ganigeorgiev]

@timololipop For the requirements check you'll have to copy the requirements.php file in the base application directory, something like:

cp  /path/to/your_presentator/vendor/presentator/api/requirements.php /path/to/your_presentator/requirements.php

and then call with php /path/to/your_presentator/requirements.php

The database healthcheck means only that the application was able to connect to your DB with the configured credentials.

Could you attach a phpinfo dump/screenshot?

@timololipop The requirements check seems ok (if you are using MySQL). Could you provide more detailed server log(s) of the error?

You could also enable temporary dev and debug mode on application level by changing YII_DEBUG to true and YII_ENV to dev in your web/api/index.php.

The sign up process seems to work now, but I got problems with the Mail Setup.

'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'useFileTransport' => false,
// Sends all mails to a file/db by default.
// You have to set 'useFileTransport' to false and
// configure a transport for the mailer to send real emails.
// eg.
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.ionos.de',
'username' => 'mail@mydomain.de',
'password' => 'mypassword',
'port' => '465',
'encryption' => 'tls',
],
],

https://www.ionos.de/hilfe/e-mail/allgemeine-themen/serverinformationen-fuer-imap-pop-und-smtp/

I also changed usefiletransport to false.
I dont receive any mails.

[ganigeorgiev]

@timololipop I'm glad that you managed to fix the error.

useFileTransport must be set to false for sending real emails. Unfortunately I'm not familiar with the mail server provider you use, but you could try replacing tls with ssl. If that doesn't work, to ensure that the issue is with the mail configuration and not your Presentator installation, you may want to test with mailtrap.io. If mailtrap works fine, than my suggestion would be to contact your mail server support to check if something additional need to be done at their end.

p.s. Currently activation emails can't be resent (will be added in the upcoming releases). You could manually activate your newly registered user by switching the status flag in the user table from inactive to active.

[timowevel1]

Also tried gmail, didnt work. I will try mailtrap, thank you!

[timowevel1]

Weird, they appear in mailtrap, but gmail or 1und1 didnt work.

[ganigeorgiev]

@timololipop If you are seeing your mails in mailtrap, than the issue must be something with your mail server configuration. The last time I checked personal gmail accounts had some security restrictions and limitations for the number of allowed outgoing emails. For 1und1 I'd advice you to contact their support and ask them if something additional need to be done in order to be able to use their smtp server.

[timowevel1]

Can you recommend any email provider you know it is working?

[ganigeorgiev]

@timololipop I have previously successfully tested mailgun, sendgrid, aws ses. But really any mail provider should be fine. Contact the 1und1 support and ask them for the proper smtp configurations (their documentation could be outdated, the port/host could be different, etc.).

[timowevel1]

I managed to get it working with "Mailjet". Thank you so much!
