Projectshwsw plugin installation error

I have a problem installing theprojecthwsw plugin
when I go to settings, devices and services, add integration and search for hwsw projects it finds it, but when I enter ip and port i.e. 192.168.1.236 port 8087, it gives me the error “unexpected error”.
can you help me solve the problem? I am also willing to connect with any desk if you can give me support. Thank you
