i just moved my whmcs 7.5.2 from old server to hestiacp (php fpm 7.2, nginx, mariadb 10.6 )
all work except domain checker/whois lookup on client side (when ordering).
on admin side i can search domain/whois lookup dll. and when client search domain , it recorded on whois lookup logs, but the result doesn’t show in client side (order form)
i can not find any error on phpfpm, nginx or mariadb, whmcs as well.
i have been 2 days try to fix this error but no luck
