Can't connect to wifi "Pairwise ciphers must be AES-CCM/GCM"

[Schlossi1234]

Dear all,

i can connect to my wifi at home without any problems. At a friends place I'm not able. SSID and the pw is correct. The serial output says the following: Wi-Fi disconnected, trying to reconnect. Pairwise ciphers must be AES-CCM/GCM (See attachment). I found a setting in component config - mbedTLS - Symmetric Ciphers, but this doesn't help.

Anyone has an idea?

THank you
