SXT LTE6 internet and capsman

Hi folks,
I would need your help. I’m running a small capsman setup with 1 hAP lite and 2 wAP which are configured as access points. The internet connection was esatblished via a SXT lite5, unfortunately the bandwith was to slow, so I bought a SXT LTE6. When I connect the SXT to the hAP lite, the internet connection isn’t working. For testing purposes I have conneted the SXT via cable to my notebook, here everything works fine.

I would really appreciate your help.
This is my actual config:
