BGS5 - Self Signed Certificate Exception | Thales IoT Developer Community
November 29, 2018 - 5:11pm, 2277 views
Hello, I've been trying to connect using https into a private secure server which is using a self-signed certificate.
The connection is not being successful, throwing the following exception:
java.io.IOException: -251 SSL-Error: Bad ECC Curve or unsupported
To surpass this situation we tried two approaches:
1.In the first scenario I tried to install the certificate in the ****m like the following:
- After downloading the certificate, I used the command to 'ADD certificate for verification for HTTPS connections using the HTTPS server’s certificate file in DER format (unsecured ****)' and then executed AT^SJMSEC="file","AddHttpsCertificateUntrusted.bin". It returned OK.
- Then I tried to connect again but got the same exception.
2.On the second approach, I tried switching off the certificate verification (using Command to switch OFF certificate verification for HTTPS connections (unsecured ****)). After trying to connect again, it got the same error.
This is the result of AT^SJMSEC?AT^SJMSEC?
(It indicates that the certificate is not installed even after installing even after adding it. Am I missing something?)
Could you give me any help?
