Dear The_Zhu,
Today the old proxy, beatport_proxy, stopped working because, as you probably know, Beatport has re-enabled the Challenge.
Following your advice, I switched to Mp3tag Proxy v2.1.1. However, I discovered that since I was using Windows 10 with an outdated version of Microsoft Edge from 2018, the proxy returned the error "Edge not found". I had to update Edge to version 150.
Even after updating, I still had to restart Windows and disable Sync under Settings > Profiles > Sync. Otherwise, your proxy would always time out and return error 12002.
Anyway, I managed to solve everything, but I wanted to let you know about this in case it helps.
