Can't configure WordPress Multisite it gives 404 Error

I' m new to OLS and using OLS with GCP. I want to use WordPress multisite with subdomain I configure wp-config file it works fine but when I tried to edit htaccess file through lite speed cache plugin option and saved it and restart OLS gives 404 error


So WordPress multisite with subdomain setup is working properly until you edit the htaccess file?
May I know that 404 error happens every domains?
And what did you add to the htaccess file?
