connection setup failed

[Gawrisch]

Hello,

we are using freescout with 5 Mailboxes.
From one day to another on a one mailbox when checking the settings, he says "connection setup failed".
Nothing has changed with the configuration.
Any clue how I could fix this ?

PHP version:
FreeScout version: 7.8.33
Database: MySQL
Are you using CloudFlare: No
Are you using non-official modules: No

Does it happen all the time or from time to time?

[Gawrisch]

unfortunately the error exists since more than one week.

Following error-message in the logs.
We are not using M365. We are using Exchange on prem. All other accounts work.

Checked the troubleshooting-fetching FAQ, but still :

Date | Event | Error | Mailbox -- | -- | -- | -- Juni 17, 15:35:02 | Fehler beim Empfangen der E-Mail | Error: connection setup failed; File: /www/html/vendor/webklex/php-imap/src/Client.php (391) | Calenso HelpDesk

Did it work before?

The only way to investigate it is for someone to check on your server or you can create a temporary mail account and send to support@freescout.net

[Gawrisch]

Yes, it worked since February and without any change it stopped working. I checked again all Exchange settings.

Try to change lines 366-370 in /vendor/webklex/php-imap/src/Client.php to:

        } catch (ErrorException $e) {
            throw new ConnectionFailedException("connection setup failed - ".$e->getMessage(), 0, $e);
        } catch (Exceptions\RuntimeException $e) {
            throw new ConnectionFailedException("connection setup failed - ".$e->getMessage(), 0, $e);
        }

After that try to fetch emails again and you should get more detailed error message (post it here).

Here is the updated /vendor/webklex/php-imap/src/Client.php file, try it to get more detailed error messages:
Client.zip

Which one of these ?

/assets/install/vendor/symfony/http-kernel/Client.php
/assets/install/vendor/webklex/php-imap/src/Client.php
/assets/install/vendor/webklex/laravel-imap/src/IMAP/Facades/Client.php

/www/html/overrides/guzzlehttp/guzzle/src/Client.php

[freescout-help]

/www/html/vendor/webklex/php-imap/src/Client.php

Or you can simply update FreeScout to the latest version. It has already been published.

This made my troubleshooting much better. We deleted the account from our exchange server and re-added it. Now it works !
Great support ! Thank you so much.

[freescout-help]

Great. So what was the error message and what was the problem?

[Gawrisch]

The error message was : Error: connection setup failed: Authentication failed; File: /www/html/vendor/webklex/php-imap/src/Client.php (391)

so I thought : if he is not able to authenticate and all other accounts have the same settings and work, it has something to do with the exchange-account. So, I deleted the user and account and re-added it. Workes as charm. Microsoft is doing strange things sometimes. :-)

I am having this exact same issue, but on a brand new instance of Freescout. I have never been able to get email fetching to work. The error is identical. I've tried a couple of different admin emails (admin emails that manage MS365). But nothing seems to work. all I see is this:
Error: connection setup failed: Authentication failed; File: /www/html/vendor/webklex/php-imap/src/Client.php (391)

which is pretty cryptic. I don't know. If all else works and IMAP and SMTP are allowed already on my chosen user email acccount, I am at a loss.
