未知MySQL服務器主機

Question

一個PHP verison變化後，我有以下錯誤

Warning: mysqli::mysqli(): (HY000/2005): Unknown MySQL server host 
'clouddb.myhost.gr:3306' (2) in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 7Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 10Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 10 . 

，我不能明白是什麼問題
