Hi, hope you are doing well, yes sure. i am facing a database error it shows "error establishing a database connection" I do now know why this occur, this error did not occur every time, i also searched this on the wordpress official community and also on the Internet i found this post on the internet (https://monovm.com/blog/how-to-repair-wordpress-database/) i followed the step provided here, but my problem is same as the previous,

please check database login credentials and host , wordpress cannot establish database connection with your database server

i think sometimes database server (MYSQL Server) going offline, please check with your hosting company, if database is corrupted then showing different error, "error establishing a database connection" means cannot connect to the database
