Connection error after adding 7 day referral code

Used a referral code to get free 7 days sub (account is preferred) shows I have the subscription with 4 days left but trying to login last 3 days I get the attached connection error screen.

Allowed through firewall/anti-virus (turned them completely off same error)

SWTOR account name Monkeyface.

Thanks in advance.

Update: have been able to login a few times. Play character for a few minutes then it kicks me back to the server select screen with the connection error.

Update 2: able to play somewhat longer, then I'll click on a reward or just stay in game for about 3 minutes and get kicked to the server select screen with connection error. Then I have to reboot my router every time to get back in...for 3 minutes, rinse repeat.

Did full repair, dns flush, tried with and without bit raider and it just does the same cycle.

Never had any of these issues before adding the 7 day sub renewal.
