Hello, I am using Bcube in Jessore, unfortunately Steam client won't connect from my pc, Connection log says UDP connection failure. I have tried disabling firewall, Deleting/reinstalling steam, port forwarding from my Tp-Link router, but nothing works.

Steam only works when it launched in -tcp mode.
Origin works though.

So, my question is does BTCL/BCube block UDP connection? Any way to bypass this issue? Will TCP mode cause issues with online gaming via steam?
