I installed ansible tower on my server.
I did not know then that ansible uses port 80 and 443.
Now, my nginx server was running on port 80. I had grafana server running behind nginx.
After installation of ansible tower, I cannot access my grafana server.
This is what it says(in the picture). I stopped the tower, and then tried to access my grafana server. But it gave me a 502 response even though my grafana and nginx were running.
How can I solve this issue ?
