I will preface this with the fact I am not an ssl expert. I am trying to resolve an issue I am having with apache and a reverse proxy that I think is ssl related. Attempts to connect to the reverse proxy endpoint via a browser generate the following error in the apache log file [Tue May 29 09:14:36.494710 2018] [ssl:info] [pid 23700:tid 139947205977856] SSL Library Error: error:1408F10B:SSL routines:ssl3_get_record:wrong version number When I run the following command on the server the reverse proxy is pointing to I get a similar error *openssl s_client -connect localhost:443* CONNECTED(00000003) 140508314333632:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../ssl/record/ssl3_record.c:252: --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 5 bytes and written 176 bytes Verification: OK --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 Session-ID: Session-ID-ctx: Master-Key: PSK identity: None PSK identity hint: None SRP username: None Start Time: 1528389016 Timeout : 7200 (sec) Verify return code: 0 (ok) Extended master secret: no If I run that same command on the front end server running apache that has the reverse proxy configuration I get the following *openssl s_client -connect localhost:443* CONNECTED(00000003) depth=0 CN = 1804-repo verify return:1 --- Certificate chain 0 s:/CN=1804-repo i:/CN=1804-repo --- Server certificate -----BEGIN CERTIFICATE----- MIICzjCCAbagAwIBAgIJAPiVKPiTG4FhMA0GCSqGSIb3DQEBCwUAMBQxEjAQBgNV BAMMCTE4MDQtcmVwbzAeFw0xODAzMjIyMjUyMzNaFw0yODAzMTkyMjUyMzNaMBQx EjAQBgNVBAMMCTE4MDQtcmVwbzCCASIwDQYJKoZIhvcNAQEBBQADggEPADCCAQoC ggEBAK3w7ErX2bo7ijEx0jEGi+MzkceAIU6km0G7+q9wRJ7u7qy1HMvfynjKQnrK AmIqwPsKr4kJl4m/cn6Wv1u7E53ZEiNpjs8qO73xOS/C/Sqs0f9vbBFNu1DYGcFZ MtJVWSvPz9aPUnNu5IfL6tUI/yRThKa6YXrjOX35NxxmvK0eQMROGx9LJ8Hz9/Ld 4z0znsLgZFOQL1ssx4xDzJ6M5hnaTBOkfJn/yDiaEOH4RlRKE9rBi5BD6wPa5jIC L9SU2+1VkicWZUoYyXI4N7EYS8dznYMpVaQbUTjsKktgN0R8zZXTdF84CFkI8w11 Buacbsf8B4Ea8qqUSvVoFdreANMCAwEAAaMjMCEwCQYDVR0TBAIwADAUBgNVHREE DTALggkxODA0LXJlcG8wDQYJKoZIhvcNAQELBQADggEBAIHKZbF97JWPrw058upQ 7cngDwOOKYQDkOo1HWWfAfK2rWeBvwEDvZmebM8S6Sx9ccJxjf80o17tJA6dJ+Uz KR2ip45VCbwK64SpKAeKfnqgTEvliUV7eMCjpG6pP+MuTnKCglRtAtS9TiEddj1A h13uXDl2kInNyU+Hbk65mFRWsX4f7JTTDqMB0MCALW3H4RhnAIX5j5viyXL0qbE0 KNkM9S7sgei67RAl6XlAo/KQ8PNU5jWkjWMkGC0TdgeUI0H79R35sGBXKCWJ6w0v mqCh2C5zX9yDzKQoQaFWi0UFzknO+178rGB9FIYBkF4CliQSji8yXhWSwa4K74+M 2AE= -----END CERTIFICATE----- subject=/CN=1804-repo issuer=/CN=1804-repo --- No client certificate CA names sent Peer signing digest: SHA512 Server Temp Key: X25519, 253 bits --- SSL handshake has read 1379 bytes and written 269 bytes Verification: OK --- New, TLSv1.2, Cipher is ECDHE-RSA-AES256-GCM-SHA384 Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : ECDHE-RSA-AES256-GCM-SHA384 Session-ID: 4F1F7BFC0A73D9CF792319A42D06FB553638D774A9DE31E66A0B094876E2C379 Session-ID-ctx: Master-Key: 6274D9B869D4281E2A538171E282B74DF5476F7A1195E38E5DE6454DA14C2F57654048DC4A774985CE45F290111D976C PSK identity: None PSK identity hint: None SRP username: None TLS session ticket lifetime hint: 300 (seconds) TLS session ticket: 0000 - 54 47 a8 3a 25 5f 30 b2-4a d7 69 5a 6b 94 32 ff TG.:%_0.J.iZk.2. 0010 - 12 50 ab e7 8a 46 f4 15-2f 1d 4a 1f 8f fd 2c e4 .P...F../.J...,. 0020 - d5 1a d8 06 74 0a 26 74-3d af 2a f6 81 72 40 33 ....t.&t=.*..r@3 0030 - 9e 5a 49 a6 a4 3d c5 1c-2e 80 ea d6 30 25 00 4f .ZI..=......0%.O 0040 - 34 06 d8 38 a1 b5 2c 63-38 50 46 ac 15 36 ad dd 4..8..,c8PF..6.. 0050 - ed 10 3c 1e 35 6d 5d 11-46 ab 8f a5 51 8e 51 ea ..<.5m].F...Q.Q. 0060 - cb 22 13 7f 6e ea 8d 9b-08 07 6f 98 24 43 ab 70 ."..n.....o.$C.p 0070 - bf b6 e9 37 b0 b9 51 aa-41 96 3d 55 25 ba 17 78 ...7..Q.A.=U%..x 0080 - dc c0 d5 91 f0 4f 61 d5-c4 46 09 0b 2d c7 35 26 .....Oa..F..-.5& 0090 - ed 2d 51 90 0b 29 08 51-5a 59 19 00 b8 95 ea 16 .-Q..).QZY...... 00a0 - c2 f2 c9 ed f9 13 df a5-c4 f6 d1 69 ba 84 9a c4 ...........i.... 00b0 - bd 68 c7 f1 7f d8 60 d4-27 b4 d4 3c a4 ef cc 5b .h....`.'..<...[ Start Time: 1528389796 Timeout : 7200 (sec) Verify return code: 0 (ok) Extended master secret: yes --- closed So I suspect my whole problem stems from the *SSL routines:ssl3_get_record:wrong version number* but I have no idea how to resolve this. I have tried searching for answers, but nothing seems to help. In inherited this problem and the folks who set this up are no longer around to be able to ask questions. Any assistance would be greatly appreciated. -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
