Done. both of them. Still getting the same error.
Edit: I found out that since my internet is on a modem with multiple people before going to my router. It could be possible this is the reason it got blacklisted (IP is shared i guess?). So i think they got a trojan (Scanned my PC with Antivirus. It's spark clean) and the IP got checked. But i can't change this problem untill i move again. But thanks anyway
