I am aware of the instabilities of the Deluge support.

any love for this ?

mh funny, i run two deluge instances; one with <300 torrents and the other one with +1000. i could add the first one perfectly fine in flood, login etcetera. and as soon as i added the second one, flood immediatly crashes

i can 100% reproduce it by changing the users.db file, removing the deluge entries, and adding them back

just realized it made my 2nd deluge instance crash

When I created an account with deluge I faced the same problem, here's some additional details if it helps: The webpage loaded a green blank page with link http://127.0.0.1:3000/overview I am unable to launch flood again through the release windows executable as well as running npm start .

○ npm install & npm run build output I have tried building Flood again, but when I run npm start it exits with an error.

○ npm start console output

F:\dex\git\flood>npm start

> [email protected] start
> node --use_strict dist/index.js

Deleted users.db and reproduced the steps. • •

This is the first time the http://127.0.0.1:3000/overview completely loaded for me, but the command prompt crashed and I will have to delete users.db again 😉

[ChristopherTheBoss]

Had the same issue. Deleting the users.db from %UserProfile%\.local\share\flood\db made it so I could successfully launch flood again. Thanks @awsms & @dexter-dz the error it threw was so vague I got scared. Also the crash persisted after reinstalling flood.

[SilverNetiX]

issue is still open. and "cannot connect to the client." shows as background of the flood interface after deleting the user.db and restarting flood.

This project/experiment needs a lot more love than its getting lol

Okay so I was also getting this error however my issue was probably different. Since this isn't documented anywhere I can tell, i'll just try to be as verbose as possible here.

tl;dr my problem was I was using the wrong username/password for deluge

Deluge has 2 main API's, the RPC API and the Web API. Each of them authenticate differently. If you're anything like me you're probably more familiar with the latter of the two. Which only requires a password to authenticate, the Web UI password being sufficient.

However this project uses the RPC API which requires a username & password. Here's how you can set that up.

• First you'll need to create a user on the deluge side that Flood will use: https://dev.deluge-torrent.org/wiki/UserGuide/Authentication
• Next you'll need to ensure deluge is allowing remote connections, to enable this go to the deluge web ui then go to Preferences > Daemon > Allow Remote Connections
• While there take note of the Daemon port that is the port you'll be using when setting up Flood.
• This step probably isn't necessary but I restarted deluge to ensure these changes took effect.

Once I did this I put all the information into Flood and it just worked. Since my Flood was a fresh install I didn't bother with trying to mess with the old database, I just wiped everything and started fresh again.

a small part of this problem is that the (re)connection promise doesn't any rejections https://github.com/jesec/flood/blob/1192e14294734e3d8925da4b376e31bcc7b3fcac/server/services/Deluge/clientRequestManager.ts#L285

I was able to determine some issues by logging the errors to console. I get a Error: connect ETIMEDOUT 192.168.0.108:58846 response, so I have an issue with Deluge or my firewall, but it's criminal that these errors are being hidden
