I am not sure if this one applies, but could you try to apply the
hotfix that is shown in the following link?

Another solution would be to (temporarily) remove the following lines
from curl source code in lib/curl_schannel.c:

    if(!(connssl->ret_flags & ISC_RET_EXTENDED_ERROR))
      failf(data, "schannel: failed to setup extended errors");
