If you're connecting from inside your LAN, you must connect to the internal IP / (DNS name, if you have one internally) of the SRX.
If you try to connect from your LAN to the external SRX IP, the traffic is going to be coming into the device on an interface other than what the SRX is expecting. Given that this is a security device, it's going to toss out the traffic that it thinks is odd.
So, if you want to SSH/HTTPS to your SRX from your LAN, you need to connect to 192.186.1.1, your vlan.0 interface.
If you want to SSH/HTTPS to your SRX from the WAN (via the Internat), you need to connect to whatever the IP is of your ge-0/0/0.0 interface which you get via DHCP. Are you running any kind of dynamic DNS service to map your DHCP address to a public hostname?
Does that clear it up?
