Error when renewing Certificate "Failed to read certificate"

[MRamadanAHafiez]

Hello Bro,

              Recently, I was trying to renew a certificate but I received the error "Failed to read certificate".

I have tried it like 4 times receiving the same error.

Tried by renewing the CA first or by the child first, both cases I receive the same error.

error message attached.

Any ideas Bro,

TIA

can you verify if the private key is 'locked' (little grey icon next to the private key checkbox)?

if the key is made inaccessible, you can't make any changes to the certificate and will need to import a fresh one

also make sure you are a superuser
