Problem solved: .p12 should be used instead .pem

Still no luck with the bot login

Problem solved: .p12 should be used instead .pem

Hi fossystem1,

I'm trying to do the same thing as you were and I'm still getting a CERT_AUTH_REQUIRED error.

I've followed the tutorial at https://api.developer.betfair.com/se...28bot%29+login, and I've also, as you suggested, generated the .pfx (or .p12) file with openssl's "pkcs12" command, but I still get that error.

I've tried to make an encrypted POST request with curl, specifying the certificate and key files (separately) on the command line and I can get the session token successfully, so it shouldn't be something wrong with my key and/or cert.

Have you got any idea what might be wrong here? Has anybody else?

[Javeid_UK_2.]

Apparently, either I failed to follow the instructions to generate a cert using openssl or there is something wrong with the instructions, since after trying to generate a new cert with the Windows GUI tool it works.

The two certs I generated seem to differ in some fundamental ways, such as the intended use, which probably means that .NET refused to use the first one to authenticate an HTTPS client connection even though I had correctly told it to use it.

&quot;CERT_AUTH_REQUIRED&quot; Error

I encounter the same error.
I tried to use both PEM and p12 extension but still encounter the same error.
