Web Gui runs but doesn't connect

[AliasJester]

Hi All, I've been searching and trying to work through this for the last 24 hours and hoping someone may be able to point out something I am missing.

I have Transmission working through NORD VPN in docker on my Synology. I can test it is working by placing a torrent in the watch directory - it downloads successfully. I have the web gui operating but when I open the web gui, the status just sits as "connecting..." and does not connect.

I'm in the 30000 port numbers just to test and have them forwarded on my router and in the docker port settings 30000:30000 and 30001:30001.

I am accessing the web gui at: http://192.168.0.118:30000/transmission/rpcweb/ and that gui comes up but does not connect to Transmission.

My settings.json and log are copied below, any help or pointers on where to look would be appreciated!

[pkishino]

you don't need any port forwarding on your router..
what is port 30001 used for?
default access to the ui should be :
you can try adding /transmission/web/ at the end..

[AliasJester]

Thanks.

WEBPROXY_PORT = 30000
WEBPROXY_ENABLE = true
These are set in environment variables but I just noticed they are not captured in my settings.json

192.168.0.118:30000/transmission/web/ redirects me to 192.168.0.118:30000/transmission/rpcweb/ and that doesn't connect to Transmission

If I use http://192.168.0.118:30000/transmission/rpc/ I get a 409 Conflict

Do you know if this 409 Conflict is what I should be trying to resolve?

409: Conflict

Your request had an invalid session-id header.

To fix this, follow these steps:

    When reading a response, get its X-Transmission-Session-Id header and remember it
    Add the updated header to your outgoing requests
    When you get this 409 error message, resend your request with the updated header

This requirement has been added to help prevent [CSRF](https://en.wikipedia.org/wiki/Cross-site_request_forgery) attacks.

[pkishino]

settings.json is just for transmission settings.. the web proxy has nothing to do with that.
please show your whole docker config..

Thanks. Docker settings pasted below.

fix below

{
"key" : "TRANSMISSION_RPC_WHITELIST",
"value" : "127.0.0.1,192.168..,8.8.8.8"
},

second value is incorrect

2. check your /data/ folder and remove transmission config folder from there (you already mapped a /config volume..)
3. try after above, else, stop container, delete your transmission settings.json file, then restart

access should be fine via http://:3000
no path added

[AliasJester]

Thank for this.

1. Asterisks aren't showing in these git comments for some reason but they are there in the file. The address is 192.168.asterisk.asterisk.

2. I have deleted the "transmission-home" folder from /data/. If I remake the empty "transmission-home" folder in the mapped location, it does get populated again. This is one part where my understanding of docker and this system breaks down. Where actually is "/config/transmission-home"?

This didn't fix the issue though unfortunately.

3. I have deleted settings.json a number of times and again now. Still not working.

I have just tried a new docker install and I seem to have it working. Thanks so much for answering my questions. I'm going to test this new install and then I'll report back on the settings that I have used to make this work. I think I may have added too many non-default environment variables in my last install and caused a conflict or error somewhere.

[AliasJester]

Appreciate the support pkishino!

For anyone coming across the same issues I have pasted my new settings below. It's probably pretty standard and I must have messed something up originally.

Beyond the stock settings for anyone looking at this I added:

• LOCAL_NETWORK
• TRANSMISSION_RPC_ENABLED

Earlier I also had an issue where I was getting an "RPC Server Unable to bind" error. That was my mistake with incorrectly setting the PUID and PGID values. Just noting for reference.
