I can report an issue of the x3 v0.10, when I tested on my local MAC.
As I access to x3 panel page, it was hang on there, \\localhost:8888\panel, no login module displays.
Although it passed Check procedure successfully.
I suspected that maybe some quoted module like cloudflare or other part is blocked, as I located in China. After I dial up VPN, and access back again, everything works perfectly.
Could you please look into his ? Thank you!
