I cant forward any port except for 80

[Amelia Gajewska]

Hi, im trying to port forward a minecraft server using serveo, since i want to host it on a school laptop, and without hacking the whole network, i dont think i will be accessing school router settings anytime soon. im well aware of my extremely nieche usecase by the way. ive been trying to forward a bunch of random ports, but all of them fail to forward. "remote port forwarding failed for listen port xxxxx"

im fairly certain it might be a firewall or some other setting in the school network blocking it, but i dont know for sure, so i came here to get an answer for this. thanks in advance
