Can't access local dev server

check also the output panel in Wappler below - where the server logging is displayed - what do you see there?

Also were you able to use the server below - because I see you are using local https - so you have to have a local SSL certificate generated first to have it work. Did you follow the process with mkcert to generate those certificates?

See Local Development with HTTPS

Btw I also see you have a http link next to the https links - maybe just use a single one not both
