(Connection refused) while connecting to upstream, client

[kaiminator]

Cheers,

recently, the fever plugin does not work anymore:

Env:

ttrs as armv7 docker container (image: nventiveux/ttrss-arm32v6:master) macvlan network with class c address traefik as reverse proxy

Worked all since years but a recent update broke this.

Got an error 500 error in the nginx access log

10.10.200.4 - - [22/Apr/2024:11:04:21 +0000] "POST /plugins.local/fever/?api HTTP/1.1" 500 5 "-" "Reeder/4020.89.01 CFNetwork/1494.0.7 Darwin/23.4.0" "192.168.1.150"

end on the error.log
