Folks, I'd highly appreciate any help.

I tried to transfer my HBC (I have 100 HBC actually) from my account to Cryptopia HBC wallet by HBC withdraw option. But I discovered that I couldn't do that as the system required my 2fa being on. The problem is that my 2fa is actually on and I use it every time to enter to my account. Is anyone experiencing such issue? If yes, how to fix it? Thanks.
