You upgraded moodle to 4.1.6 from what lower version of moodle?
Sequence of upgrading php to 8.1 and upgrading moodle ... which was first?
Did you restart web services after upgrading php?
Did you run Server Environment check to assure you had all required PHP extensions and other settings?
Did you check addons (especially addon themes) for compatibility with destination version of 4.1?
You could add a line to config.php to force the site to use 'boost':
$CFG->theme='boost';
Have you purged all caches by going directly to:
https://site/admin/purgecaches.php

Hello Ken, Moodle was upgraded from 4.1.3
PHP was upgraded first
the web server was restarted after upgrading PHP
server environment check ran and all extensions are there
All cache was purged too and deleted the sessions

The most common culprits are the caches, from the browser side and the server. Purging browser cache is documented everywhere. On the server side look under the moodledata/ for directories with *cache* in their name.

The only file that contains that error:

./lang/en/moodle.php:$string['servererror'] = 'An error occurred whilst communicating with the server';

So what is default lang for site?
And what's in moodledata/lang/

All settings related to lang:

cd /path/to/moodlecode/admin/cli/
php cfg.php |grep lang

I do re-call that in upgrading, sometimes see a notification about checking/re-aquiring language packs.

Try going directly to:
/admin/tool/langimport/index.php
and click button that says:
'Update All language packs'.

I followed these steps and this is the result of getting the language from the command line:
filter_multilang_converted 1
fullnamedisplay language
alternativefullnameformat language
autolang 1
lang en
langmenu 1
langlist
langrev 1699868808
langcache 1
langstringcache 1
doclang
filter_multilang_force_old 0
autolangusercreation 1
langmenuinsecurelayout 0
langotherroot /var/www/moodledata/lang
langlocalroot /var/www/moodledata/lang

and I visited /admin/tool/langimport/index.php directly and got this message:
Your server does not seem to fully support the following languages:

English ‎(en)‎
Instead, the global locale (en_AU.UTF-8) will be used to format certain strings such as dates or numbers.

then I clicked on Update All language packs button and it displayed "All your language packs are up to date, no update is needed"

and still the same error exists.

Think this is important:
"Your server does not seem to fully support the following languages:
English ‎(en)‎
Instead, the global locale (en_AU.UTF-8) will be used to format certain strings such as dates or numbers."

So how many languages do you have installed?
In my 4.1.6+ I see no en_AU in the list of languages.

What is in /var/www/moodledata/lang/
Actually go look and do an ls -lR there.

Install and another 'en_whatever' language.

Also ... Go to Site Admin, Server, Environment check.  Update component.

php_intl must be installed and enabled

en_AU is the default for Moodle - according to the language FAQ doc.

Your profile shows you hail from Egypt.   Are you using other languages in your Moodle site?
Did you customize anything language in your Moodle?
Those would show in moodledata/lang/local_lang/

en_AU is installed on the server and there no other languages using in Moodle site and there is no folder called local_lang in /moodledata/lang/

Make sure your moodledata/sessions diretory is rwx by all.

0 in local lang is ok ... means you haven't customized anything language on your site.

If you can, go to:
/admin/settings.php?section=langsettings
directly.

What is language autodetect set to: should be yes.
What is default language?  default should be en

There is a scheduled task
/admin/tool/task/scheduledtasks.php#tool_langimport-task-update_langpacks_task
Update all installed language packs
Does that show it ran?

In installed language packs, if default, there would be only one
in the "installed language packs' box on the left of
/admin/tool/langimport/index.php
That should be 'en' and is en_AUS.

*** Look at available language packs on that same page and select something appropriate for your site.

Well, think we've covered moodle ... but in re-reading what it says ..."Your server does not seem to fully support" that's php/operating system.
So do you have your php set to use some other language?
