It's not a firewall issue. I have it too and I've been botting for seven months now, all settings in my network (so thats including my firewall) are unchanged from when it was working. Not to mention all the users having the same issue at the same time. Besides, I might be a newbie coder, but I think I know my stuff when it comes to networking due to my job field and certification.
Also I attached my log file.
