504 gateway timeout when apply DHCP conf
-
hi,
We have 90 static DHCP entries for a specific VLAN. Last week, we added 3 more entries, but when applying, the following error occurred:
2023/10/23 13:23:04 [error] 30560#619624: *1 upstream timed out (60: Operation timed out) while reading response header from upstream, client: xxx.xxx.xxx.21, server: , request: "POST /services_dhcp.php?if=opt13 HTTP/2.0", upstream: "fastcgi://unix:/var/run/php-fpm.socket", host: "pfmaster.intra", referrer: "https://pfmaster.intra/services_dhcp.php?if=opt13"
How can I debug the error and try to obtain more information?
