Regarding recent tracker issues

We have been making tracker adjustments recently, and the latest tracker address is: ****
The old tracker address will remain, but when you encounter red or yellow torrents, you can try to change the current tracker address, https and http can be interchanged until normal.
Note: You must insert the passkey to replace the tracker!

Currently the tracker is still being adjusted, please wait patiently for the red torrents to recover
