Cannot connect to server

I recently change my network router from SKY HUB to BT HUB, after this my PS4 no longer connect directly to my server.
My server is set up on a laptop via wifi at IP : xxx.xxx.x.50
and the PS4 is set up via LAN at IP: xxx.xxx.x.105
I tried with another laptop under same wifi, ''xxx.xxx.x.50:32400" doesn’t load up.
Any suggestion to fix this ?

RESOLVED
Found out the its the router limits DNS rebinding. Disable secure connection to allow it connect locally
