Connection limit from the same Ip address?

Is there any limit for the connection from one IP or sub-network? I work with the school, they have about 25 kids in the class and connection comes from the scholl network (different accounts and decices)., we gonna play 30 min arena tournaments Very often Lichess website becomes inaccessible and connection will be possible after 30 min approx.

Is there any connection limirs, how we can solve this problem?
