Cannot access web gui on 80 anymore

Hi,

as per title, I can only access web gui if I change the port to anything than 80.

I tried the different solutions found in the forum but no luck. I run omv-firstaid and update web gui etc but nothing.

netstat -tulpen | grep 80
tcp6 0 0 :::80 :::* LISTEN 0 31082 3703/nginx -g daemo

Thanks for any help

no error, it is like no service is running and the browser cannot connect.

What is strange is that i cannot go in "http" as it is automatically changed into "https" (i checked nginx conf and OMV conf and there is no force for SSL).

I also tried different browsers (e.g. tor, navigating privately etc) but no luck.

I can work as normal if i change port to e.g. 81
