php 7.1, curl, wrong signature length when proxying through Fiddler

Hello,  when I'm developing I normally use a Fiddler proxy to see request from php CLI to remote http server. I had put a Fiddler Root certificate to CAfile.crt but I got curl_exec() failed: 35: error:04091077:rsa routines:INT_RSA_VERIFY:wrong signature length If I go directly without proxy to IIS https server the problem doesn't occur. If I check end certificate that on the fly generated Fiddler, I get no error: c:\prog\OpenSSL-1.0.2g\bin\openssl.exe verify -verbose -CAfile CAfile.crt c:\tmp\Vavra-PC.crt c:\tmp\Vavra-PC.crt: OK If I disable ssl certificate verification $defaultOptions[CURLOPT_SSL_VERIFYPEER]=false; $defaultOptions[CURLOPT_SSL_VERIFYHOST]=0, then everything is fine and I see requests in Fiddler. Tis is  Vavra-PC.crt -----BEGIN CERTIFICATE----- MIIG5zCCBM+gAwIBAgICQg0wDQYJKoZIhvcNAQELBQAwgZYxCzAJBgNVBAYTAkNa MRcwFQYDVQQIEw5DemVjaCBSZXB1YmxpYzEnMCUGA1UEBxQeSG9ybm9rcmNza2Eg MTU7IDE0MCAwMCBQcmFoYSA0MScwJQYDVQQKFB5Tb2Z0d2FyZTYwMiBhLnMuIFtJ QyA2MzA3ODIzNl0xHDAaBgNVBAMTE1NvZnR3YXJlNjAyIFJvb3QgQ0EwHhcNMTYx MjIzMTMxMDUxWhcNMjYxMjIzMTMxMDUxWjBfMQswCQYDVQQGEwJDWjEXMBUGA1UE CAwOQ3plY2ggUmVwdWJsaWMxDjAMBgNVBAcMBVByYWhhMRQwEgYDVQQKDAtTb2Z0 d2FyZTYwMjERMA8GA1UEAwwIVmF2cmEtUEMwggEiMA0GCSqGSIb3DQEBAQUAA4IB DwAwggEKAoIBAQC3f7kytRKOBFBWIH+LNWa6uGF0ZOh5qS3FykeuMfFvGIwhtlkX I50/CQd4AOe78yIExc23PXbEJBuIjS14WuFUql7cJPSn+x/607DZThSMfPzOyk0X BSALvAXc2jxaIXDyNkiKSkuauzgaQd+rQrCGYUNtj5WTviuH2W72SDS6HBZKs38k q3d0LjKvioPbZhtjbL87YZE2K6dN+qLNBnl3s+OSLsAgMwZziV1uotaH3Ca5UXDE 1wa0hH1OqzCZanztsM3E6LcvTpcQPf4mBmLvL/wKAoFnntXAXk+6fF3iawphtCpc hdWCGNax82+Ph3WJaqOJ/FRxa6muo28i8V5/AgMBAAGjggJzMIICbzCBywYDVR0j BIHDMIHAgBTMS8k0Um/V/SYot+e4KQ4iOxW2EKGBnKSBmTCBljELMAkGA1UEBhMC Q1oxFzAVBgNVBAgTDkN6ZWNoIFJlcHVibGljMScwJQYDVQQHFB5Ib3Jub2tyY3Nr YSAxNTsgMTQwIDAwIFByYWhhIDQxJzAlBgNVBAoUHlNvZnR3YXJlNjAyIGEucy4g W0lDIDYzMDc4MjM2XTEcMBoGA1UEAxMTU29mdHdhcmU2MDIgUm9vdCBDQYIJAPOG ts1i7uL3MB0GA1UdDgQWBBQSHRpoftT1jfcyDWClBLDUbcR+/zAMBgNVHRMBAf8E AjAAMAsGA1UdDwQEAwIF4DB6BggrBgEFBQcBAQRuMGwwMAYIKwYBBQUHMAKGJGh0 dHA6Ly9jYS42MDIuY3ovY3J0L3N3NjAycm9vdGNhLmNydDA4BggrBgEFBQcwAoYs aHR0cDovL2NhLnNvZnR3YXJlNjAyLmN6L2NydC9zdzYwMnJvb3RjYS5jcnQwaQYD VR0fBGIwYDAqoCigJoYkaHR0cDovL2NhLjYwMi5jei9jcmwvc3c2MDJyb290Y2Eu Y3JsMDKgMKAuhixodHRwOi8vY2Euc29mdHdhcmU2MDIuY3ovY3JsL3N3NjAycm9v dGNhLmNybDBfBgNVHREEWDBWggt2YXZyYS5sb2NhbIIJbG9jYWxob3N0ghg9d3d3 LnZhdnJhLnNlY3VzdGFtcC5jb22CGD13c2MudmF2cmEuc2VjdXN0YW1wLmNvbYII VmF2cmEtUEMwHQYDVR0lBBYwFAYIKwYBBQUHAwEGCCsGAQUFBwMCMA0GCSqGSIb3 DQEBCwUAA4ICAQBZ3E+jz2+XmaqWfCFm5Ic2/tVS3Mklhni+NchnxAtmA9hElWmq o0LL9ObnK+tdm1IC1+Hkdzv3y8yLKwuLn4sIMvJzDYGx1QD5dv8VEBax3upyJFN/ sjav4B9IDKJwcq84mYn4FSVjJhwkIiaByiPavNVW7I4r8Q0r3wGlFotzHCJf176c OoHDc6oYFR7JQeRc6z7gVnooN87sXPh44I67lPNztohB4axxuN5aeOyhWrs4/Tgd 71t2VsvI+xehPnsRXJ0oRmMzs6WIUD+NwnyRJwtCvPKqtQvhjBNjhIbg6H+tRFax eThdqqs2pB9xqVywedLqtTq8oMQ+2Z8VpxmkdSK5Sjzh/zcRcEkp8tYcV6IGi6ZU d+PC3lh6T9vzfsAJ3cu1OTpBtsgxNQQyyiP1JKNCLVa+t2NkpxiBXSMC+Kv6rtpS ZL0ZQ7Gmft2Nvn7dF9oqoCDz+D91xSAnhTsGAiOd/Rsk6j3ESykyZbC4u/ZP7eAW XLkJCWz1sGfSlMqjNsvRJV20kcvMsL2QyZeiNPpSmVL4wA4mCbCoTWFjhiEeWuFm nmRMbghmDYNi5SvYzNKT9TTjA5BLTreuuJJbN4IiUrZfZTxfg4+jzDu51b53py0T rMop++W1CoN9qSZ+mLwMJnKUobp4PNxfoJhhnWe1zGTKY2QPnEis8uusmQ== -----END CERTIFICATE----- PHP is PHP Version 7.1.12 System  Windows NT VAVRA-PC 10.0 build 15063 (Windows 10) AMD64 cURL Information  7.56.0 Host  x86_64-pc-win32 SSL Version  OpenSSL/1.0.2m ZLib Version  1.2.8 libSSH Version  libssh2/1.8.0 Any advice?
