Its likely the port you are using.  That port is commonly used for trojan horse viruss so the HomeCare service may see it as a threat and be blocking it.  Have you tried any other ports like 8080?  Also you have another option available for you.  If you link your router with a TP-Link Cloud account you can log in and manage the router remotely through its cloud access.  To do this log into the router under Basic > TP-Link Cloud, then register or log in if you already have a cloud account.  From there download the TP-Link Tether app.  Log into the same TP-Link Cloud account and you will have remote access of your router.
