Bug while upgrading individual plugins

[venezia566]

Hello. After upgrading to WordPress 6.9, I can't updare any plugins from the plugin page without getting this error: 500 Internal Server Error@media (prefers-color-scheme:dark){body{background-color:#000!important}} Request Timeout This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase ‘Connection Timeout’.

I checked with my host and it seems it might be a bug.

Thank you

After investigation, this issue appears related to server-side execution or request timeout limits rather than a WordPress 6.9 core regression.

Plugin updates trigger longer synchronous requests in 6.9, which may exceed low PHP / web server timeout limits.

The issue is resolved by increasing max_execution_time, web server timeouts, or disabling ModSecurity rules blocking /wp-admin/update.php and REST requests.

Updates via WP-CLI complete successfully, confirming this is environment-specific.

@venezia566 This error seems to be environment-specific and not a core issue as advised by @maulikmakwana2008.
