Centos 8 Curl problem!

Post by jambo » 2020/06/25 21:40:33

I have version 8.1.1911 installed and every time I try to use curl from the installed system, BACK TO the same installed system I get the following error:

curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

I have verified that I am running tls1.3 on Apache by using my web browser and using my mac to curl to the server itself.

I have curl version 7.61.1:

I have libcurl version 7.61.1:

Any help is greatly appreciated as this is affecting my operations big time!

You running a proxy (post your curl with the --verbose)?

I guess you could use openssl s_client -debug -connect <host:port> to diagnose further
But note that curl could be compiled with many different providers (OpenSSL, GnuTLS etc.).

Mine uses OpenSSL:
$ ldd -v $(which curl) | grep libssl
libssl.so.1.1 => /lib64/libssl.so.1.1 (0x00007fd2e0842000)
libssl.so.1.1 (OPENSSL_1_1_1) => /lib64/libssl.so.1.1
....
