Hi!

I ended up with the same issue. If you have the openssl tools available, you can extract the thingname directly from the certificate. It’s embedded in the “subject”. You can try this something like this:

```auto
openssl x509 -in cert.crt -subject -noout

```

You should get an output similar to this:

```auto
subject=C = , ST = , L = , O = , OU = , CN = e74d3774-ceff-493c-b3f9-398d4e9d7585

```

Your thingname can be extracted from the CN field.
