Nginx - Solution for 10060: A connection attempt failed because the connected party did not properly respond

I was in the process of setting up Nginx to serve as the reverse proxy for Nexus Repository Manager OSS. However, the Nexus repository started loading really slowly post this and used to repeatedly display disconnected and reconnected messages. The Nginx log file used to log the below error -

<timestamp> [error] 3240#3632: *1 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while connecting to upstream, client: <ip address="">, server: <fqdn>, request: "GET /nexus HTTP/1.1", upstream: "http://[::1]:8081/nexus", host: "<fqdn>"


My nginx.conf for this context path was -
location /nexus {   
proxy_set_header        Host $host:$server_port;    proxy_set_header        X-Real-IP $remote_addr;    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;   
proxy_set_header        X-Forwarded-Proto $scheme;    proxy_redirect http:// https://;   
proxy_pass http://<fqdn>:8081/nexus; # though this was the same VM, I used FQDN here
}

After spending a significant amount of time, I finally came across a really simple but non-obvious solution here. It was to change proxy_pass to;
proxy_pass http://127.0.0.1:8081/nexus;
Quoting from the linked document -
There might also be an issue when using domain names which are external while you are internal to Nginx, ea. All traffic going out through a router and back in again, use a local DNS (or your ‘host’ file to keep such traffic local) 
Now the Nexus repository does not have any access issues. Loads blazing fast.

SSL VPN: Configuring and Using Forticlient on Ubuntu, creating a Launcher

Is your primary OS at home Linux and do you use Windows only to connect to your work PC over VPN or to attend meetings? Do you often wish to connect to your work VPN from a Linux PC?  If your answer is 'Yes' to the above questions, I have an answer if your workplace uses Fortinet SSL VPN. Note that it's possible to connect to Fortinet and other VPNs like Cisco VPN from Linux through the inbuilt network manager by installing additional tools but this post would focus on using the standard Forticlient for accessing the resources on your work network.
Obtaining Forticlient The most important thing to note w.r.t. using Forticlient for Ubuntu (or any Linux distro) is to note that the client is not publicly available for download from the official website. You will have to ask your IT department to download the client for you, in case they haven't provided it.
