Other details

I've had this setup working for about a year now, never had issues.. I dont know what could have changed on my system for it to stop working... I've allowed spotdl.exe in my firewall a long time ago and doing it again didnt fix it. Should I do Uvicorn instead/also? Using the .exe for the WebUI (version 4.2.0) was able to fetch song and download it. Could it be that the client ID/secret of my config need to be changed/updated? Thanks for any help!

Hello, i just installed and got the same error, is there a solution?

i also got this error when i was changing some setting on casaos

Hi, I noticed the same error. I found in the "inspect/developer mode" that some calls were going to port 8800, instead of 8877. I am using the docker image, so instead of publishing the port 8877 to 8877, I published the port 8800 to 8877 and started working again.

Edit:
When I run the docker image, I use the port 8877 "--port 8877".

So I just updated and made a new config.. @cumal is definitly onto something because when using the default port 8800, I'm able to fetch and download songs from the WebUI, changing the port to anything else breaks it.. I don't know why that is the case, I've had it working on port 8098 for a very long time. Also, am I dumb or is there a way to run the WebUI in a docker container? Thanks
