wikimedia 1.35 on linux debian, php 7.3
what possibly could give a client side ERR_CONNECTION_RESET editing a sub section, no apparent errors server side, editing the entire page works properly, I intentionally disabled https, plain http is enough inside a secure lan
thanks for any hints whatsoever where to look possibly
Did you look at your webserver error logs (apache error logs, php-fpm process logs...)? A connection reset may indicate the webserver or (more commonly) the php engine crashed while processing the request (usually with a SIGSEV signal, or "segmentation fault"). If that's the case, this may happen due to a buggy php extension installed, sometimes related to php caching.
I have this at the beginning of LocalSettings.php :
error_reporting( E_ALL );
ini_set( 'display_errors', 1 );
and at the end :
$wgShowError = true;
$wgShowErrors = true;
$wgShowSQLError = true;
$wgShowSQLErrors = true;
$wgShowException = true;
$wgShowExceptions = true;
$wgShowExceptionDetails = true;
$wgDebugComments = true;
$wgDebugLogFile = "/var/log/mediawiki/logfile.log";
no errors in /var/log/apache2/error.log

I can't find any "error" or "segmentation" what should I look for say "timeout" ?
/var/log/syslog also nothing apparent :

it is php 7.3, how to configure php-fpm ?
If you are using apache, you're using apache-mod-php and not php-fpm.
Looks like you can discard a segmentation fault at this point. It may be an intermediate firewall or proxy (mis)detecting some weird thing and resetting the connection. Only you know the different devices/software between your browser and the server to know what could be. A network inspecting tool like Wireshark or tcpdump can be used by an expert to check on both server and client from where the connection reset originates.
from wireshark, after the POST there is a red RST, connection dropped I suspect from server side, the strange thing is that editing the entire page works
if possible to delete previous message, it should be :
from wireshark on client side, after the POST there is a red RST, connection dropped I suspect from server side, the strange thing is that editing the entire page works
