I understand that you have to do a lot of guessing here.
It might be a long time before we get there, but if we still have trouble after we are able to update OpenSSH, perhaps we can pay for some support
to find a real fix.
Regarding libssh2, I am pretty sure we are using it. Here is the output from "curl --version"
curl 7.67.0 (powerpc-ibm-aix6.1.9.0) libcurl/7.67.0 OpenSSL/1.0.2t zlib/1.2.11 libssh2/1.8.2

I doubt that will fix your issue. I rather suspect that you face this because your OpenSSH is *too new* or at least that it uses a configuration/setup that your version of libssh2 doesn't quite work with.
I think you can fix this by changing your OpenSSH config or updating your libssh2.
If indeed you are using libssh2 in your curl build.
This is a fair amount of me guessing though.
