Trouble with Nginx configuration - nginx

Question

I am running a few services from my VM at home, and I'm having some issue in connection with bad bots and setting up a https redirect for my subdomains. I would highly appreciate any help in fixing these issues.
The bad_bot issue is that if I enable it in the Nginx file, it won't let me open the webpage from any browser (throws a 403 error). The code is below:
map $http_user_agent $bad_bot {
default 1;
"~*\bUptimeRobot/2.0\b" 0;
}
The other issue is that if I visit any of my subdomains by typing out the link in a browser, it redirects me to Port 80 instead of Port 443 by default. I would like to redirect to Port 443 for all cases. My default file contents are below:
include /etc/nginx/blockuseragents.rules;
include /etc/nginx/bad_bots.rules;
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
#server {
# listen 80 default_server;
# listen [::]:80 default_server;
# server_name *.example.in;
# return 301 https://$server_name$request_uri;
#}

Answer 1

Your map directive is back to front. You also need to move the ~* outside the quotes of your regex.
map $http_user_agent $bad_bot {
default 1; #This sets $bad_bot to 1 is nothing else matches
"~*\bUptimeRobot/2.0\b" 0; #This sets $bad_bot to 0 if the regex matches
}
So at this point, if you fixed your regex then UptimeRobot would be $bad_bot 0 and everyone else would be $bad_bot 1
It's not looking good for most people when they get to this part of your config:
if ($bad_bot) {
return 403;
}
