MMS failed to send eos 1.21

Hi

My phone: Murena 2
eos version : 1.21
my carriers : Sosh(orange) main carrier, Free pro second carrier

I used to be able to send mms with the sosh number with no problems, but since 1 or 2 month it failed everytime
i checked the apn settings but nothing is out of the ordinary
i tried to ping the mms server name mms.orange.fr with a terminal emulator but it don’t seem to work, maybe the problem is here but i don’t know how to resolve it

tried to reboot the phone / setting and unsetting the two sims but nothing work
