Firstly, you posted a 2048-bit certificate, which would not normally
fail with a "key too small" error, other than by failure to parse
the public key.

Secondly, when I start the OpenSSL 1.1.0 s_server(1) with the posted
certificate as the chain file, and a random 2048-bit RSA key as
the key file, the error is that the key and certificate don't match.
This means that at least s_server *is* able to parse the public
key.  Are there some other certificates in the chain file, in
addition to the leaf certificate you posted?  Please post all
the certificates (but not the private key) from that chain file.
