The cause of your problems can be found in the config that you posted. As for the access via HTTPS look at these lines:

ip http access-class 2

ip http authentication local

ip http secure-server

This says that access via HTTPS must be permitted by access list 2 which permits only the addresses of VLAN 1 to access it and denies any other access:

access-list 2 remark HTTP Access-class list

access-list 2 remark SDM_ACL Category=1

access-list 2 permit

access-list 2 deny any

The SSH issues is in the config of the vty lines. You do have them configured so that they accept SSH but not telnet. But you have put an access restriction on the vty lines with this:

line vty 0 4

access-class 23 in

which says that any SSH access must be permitted by access list 23. But there is no access list 23.

So to permit HTTPS you would need to add your source address to access list 2. And to permit SSH you must create access list 23 and it must permit your source address.
