SARA AFF R412 data output to mock API

Hi all,

So far I’ve managed to connect the board to the KPN server following the passthrough steps.
The strenght of the connection is around 20,99 and for the next part i have to get some output on a beeceptor mock api.
I’ve readt through most of the datasheet relating to AT-commands and tried a lot of variations with udp and tcp but most of the time im getting the no permission return.
Anybody that can guide me into the right direction regarding the right AT command and setting would be great!

Many Thanks,
Dave

Progress and output.

AT+URAT?

+URAT: 7

OK
AT+CMEE?

+CMEE: 2

OK
AT+CGDCONT?

+CGDCONT: 1,“IP”,“internet.m2m”,“XX.XX.XXX.XXX”,0,0,0,0

OK
AT+CSQ

+CSQ: 18,99

OK
AT+USOCR=6

+USOCR: 0

OK

These were the initial steps the SODAQ passthrough page listed.
But from this point on im still stuck.

AT+UDNSRN=0,“myendpoint.free.beeceptor.com

+UDNSRN: “IP”

OK

After this i’ve managed to get the socket to connect to the ip adress.
AT+USOCO=1,“MYIP”,80

OK

+UUSOCL: 1
AT+USOWR=1,5,“Hello”

+CME ERROR: Operation not allowed

AT+USOWR=1,12,“Hello”

+CME ERROR: Operation not allowed

AT+USOWR=1,12,“Hello world!”

+CME ERROR: Operation not allowed

but when i try to send a message to it the operation is not allowed.
Do i need to do an additional step or a different combination all together?
