Port opened but still closed

[christ]

Hello

I am completely puzzled by what I am experiencing.

First I assigned a static IP to my computer (192.168.1.101), then I went to portforward.com and opened port 18984. Now when I run the speed test (ALT + G) it tells me that all is well, but the triangle icon just won't turn green. And when I go to canyouseeme.org it tells me that the port is not open. I even went into the advance settings of windows firewall and added the port just be sure. When that didn't work I disabled Avast along with windows firewall. Still it says that my port is not open. I have no idea what is wrong

Running the speed guide will increment (or decrement) the port, and if your router does not support automatic port mapping (UPnP or NAT-PMP) the new port number will remain closed.

But it does support UPnP. I even tried disabling it, but then the speed guide told me the port was closed, but after re-enabling it's listed as open. Not by canyouseeme though.
