hey everyone I am a new to Linux. I have installed archivematica on my VM using VMware Workstation. I have followed the guide below, but when i try to access this machine using its IP address which is 172.16.0.12:8000 or even without the port number, I get the error message

502 Bad Gatewaynginx/1.18.0 (Ubuntu).

even when i use curl i get the same error

https://www.archivematica.org/en/docs/archivematica-1.13/admin-manual/installation-setup/installation/install-ubuntu/#install-pkg-ubuntu Here are some of the logs

arch@archeieve:~$ tail -f /var/log/nginx/error.log

And here is the configurations' lines of the IPtables

Chain ufw-user-input (1 references)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8000
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8002
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:https

what are the main steps to identify and solve this problem?

From what i know This error " failed (111: Connection refused) while connecting to upstream " means that the service that nginx wants to pass the connection to is not up or not responding bellow timeout limit.

So check that the services listed in the tutorial that you linked are up such as

sudo systemctl status archivematica-mcp-server
sudo systemctl status archivematica-storage-service
sudo systemctl status archivematica-dashboard

If one of them is not started ( active ) then investigate why it didn't started
