Problems with Wirelees Projection

Hello good morning, I have a problem with my computers when trying to project on a wireless screen, my computers have Sophos Intercept, Sophos mobile used this for the remote erase issue, and they go to the internet through the XG-230. If I connect a device to the same access point without (mobile and Intercept) but with the same output through the firewall. it is projected without major problem. But if I try to connect my computers with Intercept and Mobile, the connection cannot be established.
