May be you can try delete all old certs :
no crypto pki trustpoint TP-self-signed
no ip http
no ip http secure
Then config :
ip http
ip http secure
You can issue below command check the ciphers :
show ip http server all
or you can also configure ciphers you want to :
ip http secure-ciphersuite ? (give you options)
and when i reload, my config is gone...is very frustrating sometimes..
If you do not read the documents then you will go more fustration.
show version ( check the config register - setup correctly to retain the config).
config-register 0x102
no system ignore startupconfig
