Try to connect to 802.11 with SXT 5 ac

Moin everyone,
I hope i am writing in the right corner of this forum.I try to establish a backup link for my internet connection at home. And as a Student who lives on the other side of the street of a university building I decided to use eduroam. For my setup i took mikrotik sxt 5 ac which tries to connect to eduroam. Sadly i always get a deauth. U can see my settings in the files attached and the guide from my university is:
Security: WPA & WPA2 Enterprise
Authentication: Protected WAP (PEAP)
CA certificate: T-TeleSec_GlobalRoot_Class_2.crt
Inner authentication: MSCHAPv2
Username: @xxxxx.de
Password: Passwort der xxx-Login-ID

Can you helpme ?
