qbittorrentvpn ERR_EMPTY_RESPONSE

[Imstuck192]

Hi, I have been running the qbittorrentvpn docker container successfully for some time.

The image used is the markusmcnugen version.

Recently there have been two power cuts while the container was running on a synology NAS 1019+ DSM 6.2.4-25556

After the first power cut it was no longer possible to log into the QB webui for approximately 24 hours, eventually functionality came back.

After the second power cut despite waiting several days for functionality to return the webui remained inaccessible with the following error:

"synologynasip" didn’t send any data.
ERR_EMPTY_RESPONSE.

I began the process of trying to build a fresh docker container to see if this would fix the issue, however when it came to querying the NAS for the PGID and PUID using the following command:

ssh "username"/"synologynasip" -p2299 (I have substituted the real username and ip)

I received the following error message:

ssh: Could not resolve hostname "username"/"synologynasip": No such host is known

What is strange is that the NAS is functioning perfectly fine and is accessible over the local network so it should be connectable. I am unsure why this specific issue exists and would be grateful for any help to get back to a working set up.

@Rusty, thanks I have zero experience with this and unfortunately the guide assumes some prior knowledge.

Where exactly am I supposed to run the commands in the guide? When I type them into the terminal of the running container using the docker gui within Synology's DSM nothing happens.

If I run the commands after using "ssh username@synologynasip -p2299" from CMD

The first return from "lsmod | grep tun" is:

ip6_udp_tunnel 1903 1 vxlan
udp_tunnel 2355 1 vxlan
tunnel4 2261 1 sit
ip_tunnel 13200 1 sit

However if I follow the next step "mkdir /dev/net" the return is:

mkdir: cannot create directory ‘/dev/net’: Permission denied

This needs to be run at nas level via ssh yes. Run it as root and try again. Use: sudo -i to elevate to root.

@Rusty Thank you very much for your help. I can confirm the guide to fix the tun issue worked successfully.

It's a great guide. Some tweaking for various VPN providers (in my case AirVPN) may be needed.

I was really delighted to see the added section on tapping the VPN connectivity for other containers. I plan to try that with jdownloader2 when I get the courage

@Telos FYI I was able to get the container working on docker version 20.10.03-0552 which I downloaded from Synology Archive Download Site - Index of /download/Package/Docker and had to manually install.

Yes I can see how that would be useful.

You've given me courage. I'll give it a go this weekend.

The only part of the guide I couldn't get to work was making the tun error fix persistent.
