#235 Maximum execution time of 30 seconds exceeded in /var/www/gnusocial/vendor/mf2/mf2/Mf2/Parser.php on line 1493

From nginx error log:

[error] 16422#16422: *989138 FastCGI sent in stderr: "PHP message: PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/gnusocial/vendor/mf2/mf2/Mf2/Parser.php on line 1493" while reading response header from upstream, client: 138.201.193.13, server: gnusocial.net, request: "POST /inbox.json HTTP/2.0", upstream: "fastcgi://unix:/run/php/php7.3-fpm.sock:", host: "gnusocial.net"

The error seems to be triggered by Friendica nodes. Looking at GS debug log doesn't show anything obvious...

Maybe related, this message appears recently. It's the same IP, a Friendica node:
