Freescout IMAP connection error - Error: connection failed

[semaf]

Hey,

I have an issue with the IMAP connection with type of encryption. SMTP is working fine. It is a local connection between two docker containers in same network.

How is the password forwarded? Plain, crypted? Maybe its the TLS version?

Would be about some help.

If using STARTTLS, the log: Apr 26, 15:30:02 Error fetching email Error: connection failed; File: /www/html/overrides/webklex/php-imap/src/Connection/Protocols/ImapProtocol.php (82)

Try to add APP_NEW_FETCHING_LIBRARY=true parameter to the .env file and clear cache.

I am receiving the same error:

Error fetching email Error: connection failed; File: /www/html/overrides/webklex/php-imap/src/Connection/Protocols/ImapProtocol.php (82)

This started today after upgrading from 1.8.139 to 1.8.140

I tried adding the APP_NEW_FETCHING_LIBRARY=true parameter and clearing the cache, however the error persists. I did not change any settings before or after upgrading to 1.8.140.

Any other suggestions?

I looked over the code changes from 1.8.139 to 1.8.140 and see that APP_NEW_FETCHING_LIBRARY is now defaulted to "true".

In case it helps anyone else reading this, my issue was resolved by setting APP_NEW_FETCHING_LIBRARY=false and clearing the cache.

@torrelasley What email service are you using? Can you send the screenshot of your Fetching settings.

In the future the old fetching library will be removed, so better to make sure you are able to fetch via the new library.

Try the following: 1) Remove APP_NEW_FETCHING_LIBRARY parameter from the .env file. 2) Clear cache. 3) Go to your mailbox's "Fetching Emails" settings and try different "Encryption" options:

I followed your steps and removed APP_NEW_FETCHING_LIBRARY and cleared the cache.

Switching to STARTTLS worked for my system!

Note that you must click "Save Settings" after making the change before pushing the "Check Connection" button. At first I thought none of the Encryption settings would work until I realized this.

Unfortunately I didn't take a screenshot before I made the change so I don't know how it was previously set. Thank you for your help!
