Hello all created an acc just to help my fellow Malaysian GTA gamers out there. Unfortunately, firstly,  I think this only works for TM Unifi users. Secondly this might not help some of you as it has helped me.
So after chatting with the TM live technician after diagnosing the problem by instructing me to download Ping Plotter from http://www.pingplotter.com/ to view the problem it was found out take two was indeed the source of blocking connection.
The DNS ( was set at Auto or all 0's) was causing the issue of me not being able to connect to social club. The technician then instructed me to login to my router thru my computer and to change the manual setting of my router's primary DNS and secondary DNS to that of which the technician instructed. It was changed to that of below:

Primary DNS : 1.9.1.9

Secondary DNS: 202.188.18.188

Note: this is apparently Unifi's DNS as they have told me.

After saving the settings it worked and could connect.

TLDR: login to TM Unifi router online find and change manual settings of primary DNS to 1.9.1.9 and secondary DNS to 202.188.18.188.

So yeah that's it. Hope it helps.

Another side note: this is with a TM router and using unifi. I am not sure if it will work for those using other types of ISP or other types of router's. Please contact your ISP if you this doesn't help as they can be helpful given enough data and prompting.

Cheers all.

Problem is I can't connect to RDR online too.

Did you change the DNS on your computer or directly into your router settings? If you changed the DNS on your computer it most probably will not work. It has to be done directly into the router settings via online.

I have used VPN for a month just to play GTAV. Just use a VPN and you should be fine.

Change ip address by
reconnect ur internet manually(quickly dc and rc in few seconds)
or restart router (takes long time)

Try to get a different prefix ip address,  if an ip is blocked, most likely ip addresses in the same prefix are the same

Or use VPN (not recommended, may violates ToS)

Or use other ISP, maxis, time

can u access GTA Online? even though if ur current ip address blocked from access social club ?

so can u go to socialclub website? using browser

since rockstar replied me about they did some necessary "changes" to my account for allowing to play rockstar games without problems

i really haven't encounter this problem so far, not sure if thats what rockstar did to my acc or they got it fixed, but not to all affected users.
