Hi,
the title is pretty self explanatory - I'm trying to play from my laptop (lenovo l13) to my PC, but when I click stream the game opens on the PC itself, but no stream window opens on the laptop, it goes blue for about two seconds and returns to "connect". No matter how many times I press, it won't connect.
For the record, my internet speed is 520mbps down, and 75mbps up, my PC is wired via CAT6 ethernet & my laptop is running on 5GHz wireless on the same network (also doesn't work on other networks).
The strange part is, remote play seems to work from my older laptop, which is an old Dell Inspiron 15.
I can list specs if needed!
Any help would be hugely appreciated, I'll paste a list below this line of things I've tried & also update the post if I find anything that works!

TRIED:
Reinstalling steam on both host & client
Restarting router
Disabling firewall & defender on both host & client
Trying different games
Trying from other networks

Thanks!
