[Fetchmail-users] gmail timeout using IMAP

[Joe Acquisto-j. <jo...@j4...>]

Having entered the modern era, I seek guidance on the following problem:
. . . 
fetchmail: 6.4.1 querying imap.gmail.com (protocol IMAP) at Tue 04 Feb 2020 09:05:20 PM EST: poll started
fetchmail: Trying to connect to 173.194.175.108/143... (log message incomplete)
fetchmail: timeout after 10 seconds waiting to connect to server imap.gmail.com.
fetchmail: socket error while fetching from gue...@gm...@imap.gmail.com
fetchmail: 6.4.1 querying imap.gmail.com (protocol IMAP) at Tue 04 Feb 2020 09:05:30 PM EST: poll completed
fetchmail: Query status=2 (SOCKET)
. . . 

A snippet of fetchmailrc is below:

-----
set logfile "/var/log/fetchmail.log"
set postmaster "admin@[mydomain]"
set nobouncemail
set no spambounce
set properties ""
set daemon 240

poll imap.gmail.com with proto IMAP timeout 10 envelope Delivered-to

    user 'gue...@gm...', with password 'someword', is 'xma...@an...' here folder 'Inbox' fetchlimit 10 sslfingerprint '11:22:33:53:84:9C:EF:6C:E2:BF:AA:A8:2A:DD:EE:FF'
------

This had been working during earlier testing, but stopped while.   I updated to fetchmail 6.4.1, being the cautions fellow I am, yet, the problem persists.  

Checked that "less secure" apps was still enabled.  Did find some "security warnings" about suspicious access attempts and approved them.  That did not resolve the issue.

Many indications on the web that gmail is particularly reluctant to play nice with others.  

FWIW there are several accounts defined in the same fetchmailrc file at another provider that work just fine in the same fetch cycle.  

Thanks in advance.
