Huawei LTE certificate invalid

Hello:
In my network we have two eNodeb with the same alarms, Cerificate invalid and Canbus Communication Failure.
The alarms ID are 26841 and 26101.
Both alarms appear after the R9 SW upgrade, I tried to clear the alarm (Certificate invalid ) following the information in the alarm description but the certificate cant be removed.
The ceritficate stauts is unloaded, but when I try to remove it it s^says is in use.
Have any of you seen this alrm before?
Any suggestion?

best regards
