Song request page does not load

PhantomBot Version:
OS Version: win10 but installed on cloud google
Java Version: 1.8.0_222
Browser and Version (for Panel Support): chrome Versión 77.0.3865.120
Stock PhantomBot: Yes (Yes if you have not modified the scripts or Java Core)

hi, i have installed the bot on google cloud following the instructions on Ubuntu 16.04 LTS Setup Guide
all works nice but the when i click on song request a new page opens IP:port/ytplayer
all time is loading the page and a red warning says ‘connection with winsocket was lost. refrresh once restablished’ but nothing happens all time trying to load
yes the botlogin.txt has the youtube api key written

thanks in advance

On the Google Cloud Console go to Networking > VPC network > Firewall rules and make sure you have allowed both the port in your url and the 4 ports above it (default is 25000-25004) to access the instance

thanks a lot. i only gave access to 25000 and 25004 thinking it was a range
i have just open one by one from 25000 to 25004 and it worked
thanks a lot for ur help
can be closed
thanks again
