Looks like a problem with longpoll, try --no-longpoll.
edit: also try cpuminer-multi, if it works I can compare.
i have executed it with the --no-longpoll option, same error it seems, also tested with cpuminer-multi with and without --no-longpoll, same result:
felix@mobile:~/local projects/cpuminer-multi$ ./cpuminer -a cryptonight -t 3 -o http://10.1.1.173:41264 -DP --no-longpoll

i have tested this with the wallet rpc port, with the daemon rpc port i get:

to me it seems the rpc request method is "login" but this only works for pools
afaik one needs to connect to the daemon and use getblocktemplate?
atleast for the wallet there is no mining related method (
https://getmonero.org/knowledge-base/developer-guides/wallet-rpc)
whereas the daemon rpc has a getblocktemplate method (
https://getmonero.org/knowledge-base/developer-guides/daemon-rpc)
no matter which features is disable it always uses "login" method it seems (no-stratum, no-getwork, etc)
edit: after taking a look at this (
https://github.com/sammy007/monero-stratum/blob/master/go-pool/rpc/rpc.go), im pretty sure for solo mining to work cpuminer(-opt) needs the getblocktemplate support for cryptonight coins integrated first
