[ANSWERED]Two Factor Authentication 'delay'

Hello folks,

This has been an on-going issue, that only seems to snowball beyond expectations.
After securing my account with the TFA method, things seemed to have been running smoother, compared to the last few weeks.
I came to notice that, whenever my account is logout on Warmane's website, and thus I need to insert an new Authentication code, this method just keeps on getting 'delayed' further and further.

Practical example:
In the beginning, the FIRST code I was given by Google Authenticator (Yes, I'm using this method, and not the email one) could be entered and account enabled.
Nowadays, the FIRST code give can, in fact, be used BUT I'll have to wait 5-15min before Warmane's website actually allows that one code to go through.

Anyone else facing this issue?
Any fixes or reports made regarding this issue?

Thank you in advance.

I am using Google Authentication everyday and I never faced a problem like this also never heard anyone complain about it before. Could be something specific to you. Try reinstalling the program.
