GL-X3000 Wireguard issue

I setup my Wireguard client on the X3000 router it connects to my home Wireguard server the vpn icon goes green but my devices connecting to router seem to loose internet and being able to connect to my home network. For internet I have T-Mobile Home 5G internet using the sim from that service in the X3000. When I was using the T-Mobile gateway with the GL-MT3000 and had no issues configured the X3000 same way I did the MT3000. Been trying everything hoping somebody else ran into this issue found a fix.

[Interface]
Address = xx.xx.xx.x/24
PrivateKey =
MTU = 1420

[Peer]
AllowedIPs = 0.0.0.0/0
Endpoint = xx.xxx.xxx.xx:51820
PersistentKeepalive = 25
PublicKey =

Change the MTU configuration to 1280 and check whether it is available.

That fixed the issue thank you so much
