Soooooo, it seems like yesterday I was just looking at it for too long. I tried exactly what you said I’m sure of it…
The config is now:
location / {
proxy_pass http://10.0.0.50:8123;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $host;
#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
#try_files $uri $uri/ =404;
}
And for anyone with the same issue, do comment out the following line
try_files $uri $uri/ =404;
Anyway resolved, a clear mind does help a lot.
