<div dir="ltr">
This week, when connecting users through a proxy server, some Google
services became inaccessible, such as Calendar, Translator, user
profile.<br>
<br>
When clicking on the services section in the browser on the Google
portal, the page does not open and then a connection error is displayed.
When directly going to the calendar section, the connection also hangs
for a long time without loading the page. At the same time, the Google
home page, mail, search work.<br>
<br>
Transparent proxying is not used.<br>
Viewing the proxy server logs did not add any understanding, all
requests are processed correctly and no errors or prohibitions are
observed. There are no other problems with the unavailability of any
sites.<br>
<br>
When connecting directly (bypassing the proxy server), all Google services work completely correctly.<br>
The platform on which the problem was suddenly discovered:<br>
FreeBSD 13.2-RELEASE-p9<br>
Squid 6.6<br>
<br>
A new separate server was deployed for objectivity and finding the
cause, but the problem was also reproduced there, its platform.<br>
FreeBSD 13.4-RELEASE-p2<br>
Squid 6.10<br><div><br></div><div>
I tried using the default configuration file (recommended minimum
configuration) to eliminate the problem in my working squid.conf, but
the problem remained
</div><div><br></div>
I repeat, the problem reproduced suddenly, no changes were made to the
proxy server configuration on our side, no problems with Google have
arisen for many years. What should I pay attention to in the Squid
configuration? Any idea</div>
