I noticed logs mentioned nginx being used from docker.

so I installed nginx as a service using ubuntu's apt package manager. using steps in this link https://phoenixnap.com/kb/nginx-reverse-proxy#ftoc-heading-3

and was able to start the frontend with release backend.

I was facing 502 bad gateway also with local backend setup with using nginx from docker, now that is also running properly by using system nginx service.

sudo apt update
sudo apt install nginx
sudo systemctl start nginx
sudo systemctl enable nginx
sudo unlink /etc/nginx/sites-enabled/default

started frontend client using yarn start inside app/client folder
started nginx with following command sudo ./start-https.sh https://release.app.appsmith.com

killed other process on port 80 , when asked in the prompt by start-https.sh

I had already logged in appsmith on app.appsmith.com with my email credentials,

when I entered those using my local frontend and release backend, it mentioned that credentials were wrong
when i went to reset password page, it showed screen, that I need to setup email service, to be able to receive reset password link https://docs.appsmith.com/getting-started/setup/instance-configuration/email#configure-email

so I logged in using google oauth, but then I am not able to logout

As I was able to start with local nginx service, that means

1. we have to update the nginx conf, so that it works for docker 's nginx
2. we have to update the readme to mention that installing nginx service is pre-requisite
