Can not connect to host

[RikkaBlue]

I use frp to access to the host. I can visit the webui on browser, which uses nginx to get https access. But I can not connect to the host with the app.

There is no error. It is just loading infinitely. I fill in the host with my domain, also the port has been changed to 443, and I also check the https option.

The app version is 4.7.5 on android pie. qbitTorrent-nox version is v4.1.9.1.

Hi @RikkaBlue , if you have a subfolder set it on qBController. If not, then it my be related to this issue

Also check the qBittorent doicumentation for reverse proxing for nginex and adapt it to your proxy. In particular, set te referer and origin headers as blank.

Similar setup (but I don't use frp, just nginx), same issue, same qBittorrent-nox version, qBittorrent Controller Pro 4.7.8.

It worked perfectly until few updates, but now just loads infinitely. I guess I have the same issue as @Rouzax has.

Same issue, not using nginx or anything in-between. Was working a couple updates ago but randomly stopped.

Version: 4.8.4 Phone: Pixel XL

I uninstalled and reinstalled the app. Also wiped and readded the server info. Still the same issue. No errors, just a continuous loading icon. I can access the server's webui via the same device under the same conditions. Just seems like the app is trying to timeout but never does.

@lgallard Perhaps it might be worth while to add a logger to the app? That way, any errors or warnings are logged and the user can either report them here or possibly even debug it on there own.

[lgallard]

@sooonmitch that was the idea of the report generator, but maybe there's room for improvement here.

@lgallard I am also having the issue with the Android App (4.8.4) "qBittorrent Controller Pro" using a Pixel 3a running Android Version 10.

When I try and connect it just spins. I have re-verified the information and re-installed the application. I verified I can access it via chrome on the phone and another device.

I do not use proxy, HTTPS or anything fancy, just local IP and standard auth. I do not use it remotely.

Please help, I miss this app :D

@CircleG0d check release 4.8.7

From what I can see in the code, issue is related to the following code which is repeated throughout mainActivity

         String url = "";

         // if server is publish in a subfolder, fix url
         if (subfolder != null && !subfolder.equals("")) {
             url = subfolder + "/" + url;
         }

         url = protocol + "://" + hostname + ":" + port + url;

If you're using nginx, you are probably using a reverse proxy of the sort: https://mysite.com/qbt or https:/qbt.mysite.com because nginx handles all the port forwarding for you.

However, this code adds the ":" + port part for you, which will not work, even though port is set to "". So you get something like https:/mysite.com:/qbt/ which is wrong. You can try 443 for the port, but nginx will not understand it either way.

This should add a check to see if the port field exists and write the ":" part only if there's a port number following it.

Another suggestion I have is to check for leading slashes in the subfolder name and, if missing, add it before the url part.

Another suggestion would be to encapsulate this code in a separate method so that any further tweaks can be done in only one place, not in about 27 places (might have missed some of them).

@lgallard I can try to fork the project and make a pull request later today.

@simplethemind nice catch. Thanks for the nginx insight!!

Same issue, I can't make it work, qbittorrent-nox 4.2.5 and qbittorrent client pro 3.9.0 (I posted first in #90).
