Channel logo requests without user agent => 403 Forbidden error

[Freddy436 0]

Hello,

I noticed that emby requests the channel logos without specifing any user-agent in the request.

 

Example request for this logo:

https://upload.wikimedia.org/wikipedia/commons/thumb/4/4e/WDR_HD_Logo_2019.svg/320px-WDR_HD_Logo_2019.svg.png

GET /wikipedia/commons/thumb/4/4e/WDR_HD_Logo_2019.svg/320px-WDR_HD_Logo_2019.svg.png HTTP/1.1
Host: upload.wikimedia.org
Accept-Encoding: deflate
traceparent: 00-0e00ed5d3e24bf0983db30b869bd06f2-c5f623eee5212cd3-00

 

Many Wikipedia servers respond with an Error 403 (Forbidden)

ERROR 403: Forbidden. Please comply with the User-Agent policy: https://meta.wikimedia.org/wiki/User-Agent_policy

Please note that wikipedia uses a CDN with multiple servers, some of the server apparently don't check for the user agent, so it "randomly" works sometimes.

Can you please make emby send a user agent (preferrably some generic/spoofed Firefox/Chrome user agent) when requesting channel logos?
