This may not directly fit your needs, but I do use Ubooquity on a QNAP TS-251 and my connection is https to the outside world.

I set up login for a few people and use a DDNS service called Cheap, even free service provides all the dns and port forwarding aspects necessary. My setup allows both http and https connections, tho I am sure Pagekite could be configured to allow only https.

Pagekite is small and in (I believe) Iceland, so their customer service is not the fastest. But their documentation is extensive, so most of the (really only a few) issues I have had were self inflicted and solved with further reading of the docs.

Anyway, just a suggestion for a reliable way to have Internet access via https. Been using them for like 6 years!



I followed the bouncing ball in the qnap container station Docker setup. I selected your version of Uboo and it downloaded the image and created the container. Again, this is my first install using this qnap setup.

I don't see a way to alter much of anything, which is probably because I an not familiar with it. When it created the container, it did have a entry for 'command' prior to the install, but I have no idea what to put in there so left it blank.

It looks like it is possible to get an image manually and then have the Container Station create the docker for it, but still see no way for customization...I am learning, but slowly, LoL.

For example you say enter "docker ps". I tried that in the "command" window and it simply errors out. Is there some other way? I ssh into the nas, but "docker" is not an executable in the path.

Hopefully someone with a successful install using the qnap container station and Uboo will be able to give me some pointers...


Just an FYI.

Instead of putting in ip:2202, I simply clicked on the link in the Docker control panel, ie


That gives me the Ubooquity logo page, but black screen with:

Sorry, you are not authorized to access any file on this server

If I then put in hxxp://,

it gives me a simple page with:

Remote server administration is not activated.

So it appears the mapping from that port to 2202/2502, etc is not working for one reason or another.

Would it help to try to activate that? If so, how?


found "docker.log" (qnap buries this really deep, LoL) Anyway here are the last few entries:

"hijacked connection" does not sound good, so am going to delete the docker/image, reboot the nas, and try a fresh reinstall.

Ok, figured the errors need to put in "docker", just "ps" :

ps =

logs or log = Same error message as before.

Setup the 2.0.2 beta via Qnap Container Station/Docker. Creates container and imports the zerpex/ubooquity-docker:latest image w/o any errors. However, admittedly a noob to Docker, I simply cannot figure out how to pull up the admin console.

The command field in the docker container panel shows:

In the browser I have tried:







Allways get:

This site can’t be reached. refused to connect.

I have done an apache restart, no help there.

It's gotta be something simple, but I sure ain't seeing it yet!



I know it has only been a couple of years since this suggestion, but was interested if there has been any thought to incorporating the 'send to kindle" feature?

Yes, it is Kindle only, but the number of kindle ereader devices out there probably rival android/epub devices.

And is it a 'mobi/azw3' issue in any way? The sendtoemail is just picking a file and sending it, isn't it?

In any case, Ubooquity is a fantastic program, but those I share my books with are actually split kindle/android users and those kindle folks are bugging me about this!!
