Can't connect to http://127.0.0.1:8866/ on Ubuntu 20.04

[donbrew]

The installer set the dotnet permissions to 744 (IIRCC). I guess just setting to 754 would have worked.
It was basically set for root only execute since it was installed with sudo.

In re reading the original post I see that the error there was "no such file" mine was "no permission". So, not the same problem, but this thread led me to my solution.

Did you install as the root userid? That is not supported.

I tried to, but it stopped because it is not supported so I started over as a regular user using sudo like the directions say. I did not purge though. I guess when I tried to install as root some stuff got left behind.

Fixed now

[mvallevand]

I tried as sudo su (on Ubuntu) and the permissions where fine, 755

The commands that the installer runs when dpkg is sudo

Code:

curl -L https://dotnet.microsoft.com/download/dotnet/scripts/v1/dotnet-install.sh -o /tmp/dotnet-install.sh
/tmp/dotnet-install.sh --channel 2.2 --runtime dotnet -InstallDir /opt/dotnet

Maybe change the InstallDir to test on another folder and see what happens on your distro.

Hi

I'm having a similar issue on Ubuntu 24.04.1LTS

The service is running but when trying to open the webapp 127.0.0.1:8866 I just get wepage not found.

Code:

nextpvr-server.service - NextPVRServer

I have removed it fully using the uninstall instructions and re-installed. I have also tried the docker method with the same results (although I don't have any experience with docker).

It's not the same problem at all your server is active. However I have no experience as yet with 24.04 i like LTS versions.

Are you running a desktop Linux and trying to use the same machine? If not you need to use the IP of your server. If it is from the desktop
from the command line check your firewall and any VPN you have running and then you can try the following and see if the return data or an error

Code:

curl -v  http://127.0.0.1:8866/
curl -v  http://localhost:8866/
curl -v  http://[::1]:8866/

run

sudo service nextpvr-server stop

then

cd ~
zip logs4nextpvr /var/opt/nextpvr/logs

and upload the created zip file.

This version is an LTS

I did all the things you suggested each gave an error. It is a desktop environment i'm running. I have forwarded the port on my router the same as I do for Sonarr, radarr etc. There is no firewall running on the machine I checked that first. I don't run a VPN on the machine either.

Sorry I was confused, I am running 24.04 with no issues

Do you remember if the original install finished, some people of trouble when either the run as root or have when they install from there home folder and not tmp and get an apt error  Since there are no logs it files it could be permission error given the 500 error

From the same .deb pack try running  sudo dpkg -i ./nextpvr-help.deb

Some other service is grabbing port 80. Run

netstat -a | less

to find out what.

[mvallevand]

NextPVR doesn't use port 80, tcp 8866 (configurable) which is connecting and udp 16891 (can be disabled). If the server couldn't be started I would still expect a log to be written.
