I have this rewrite rule implemented and it will work fine if I access to Apache

it won't give any error either.
Here is what the load balancer F5 does, F5 perform a https server for the
Apache server.
So any traffic reply from Apache on port 80 will be display on port 443 on the
end user's browser.
It's a little unclear on what ports you are actually using (you mention
port 80 and 443). Is the end user's browser requesting an http or an
https page? If they are requesting an https page but apache is serving
it as an http page, are you sure the load balancer can actually rewrite
it as an https request to pass along to the end user? Does the load
balancer handle all of the SSL encryption/decryption work to allow it to
"talk" to apache over http?
The rewrite rules below are port agnostic, meaning if the client (end
user or load balancer) make a request on port 80, it will remain on port
80. The same goes for port 443, so you shouldn't require anything
special in the rewrite rules to accommodate for http versus https.
You might want to put the RewriteCond directive directly above
RewriteRule, for better readability.

Is there a way to change the RewriteCond or RewriteRule to accommodate the
Https issues???
The below syntax was recommended by Eric Covener? and it works for going direct to Apache but not going through
the F5 load balancer.
DocumentRoot /srv/www/maintenance/
# Rewrite Rules
RewriteEngine on
RewriteCond %{REQUEST_URI} !=/maintenance.html
# Apache log files and location
ErrorLog /var/log/apache2/maintenance.error_log
CustomLog /var/log/apache2/maintenance.access_log combined
# Redirect rule
RewriteRule ^(.*)$ /maintenance.html [R=302,NC,L]
######### Local server landing page #########################
<Directory "/srv/www/maintenance/">
Options None
Order allow,deny
Allow from all
</Directory>
Thanks much,
