Rainloop Webmail Server Connect Issue
So today i had problem when my Rainloop webmail gave me the below error Solution: The Solution was simple but it took me sometime to figure out. It was related to SSL So a quick fix was to go to Admin panel of your Rainloop server e.g https://<yourdomain>/?Admin After logging in Click on Domains as show below Once you click the domain you will see window as show below Now click on your domain and you will see window as show below Now change SSL/TLS under IMAP to None for the time being and click update. Your should be able to login now. I think the issue is with SSL Certificate , it should be updated , after update you must revert the changes from None to SSL/TLS. Thanks, Salman A.

Setup Nginx Reverse Proxy for Docker
In this post we will take a look at how to setup Nginx as a reverse proxy for Docker in CentOS 8. You can also find my Youtube video on the same at the end of this post. So Let’s Start: First question , why do we need reverse proxy ? The answer is simple, if we need to run many applications or webserver servicing different pages on the same server machine, we would need a reverse proxy.Reverse proxy will run on port 80 (Default port of a non secure web server) and forward the request to webserver / application running on different ports (Other than port 80 since the default port is already being used by Nginx reverse proxy). Installing Nginx: Install Docker: Install Apache pod: Setting up and Configuring Nginx for Reverse Proxy.
