[x] For pending transactions: I confirm that I have tried reattaching and promoting multiple times (check this box if your issue is not related to a pending transaction)
[x] I confirm that this is not an issue related to stolen/lost funds
[x] For private key warnings: I confirm that I am not at risk of reusing an address, or another user has verified that I am not (check this box if your issue is not related to a private key reuse)
[x] I confirm that this issue is present on the latest version of the wallet

Description

I am unable to connect the latest version of the Light Wallet (2.5.6) to my own full node. I know for sure that I am able to connect to my node via IP, and via localhost (via port forwarding). This is confirmed via curl, as well as going to tools -> node info in the Light wallet.

❯  curl http://localhost:14265 \
  -X POST \
  -H 'Content-Type: application/json' \
  -H 'X-IOTA-API-Version: 1' \
  -d '{"command": "getNodeInfo"}'

When I try to login with a previously used seed I get a "Connection Refused" error. Furthermore, when using a new seed, it tries to connect for a couple minutes but then times out with no error.

I know my full node is using latest version as of this post (1.4.1.6) and is running the latest milestone. I am not sure why the wallet cannot connect when using my server. I am able to login using the same seeds when using a public node.

Steps to Reproduce

Open wallet
Go to Tools -> Edit Node Configuration
Host = Custom and use http://localhost:14265 or http://<my full node ip>:14265
Save
Go to Tools -> View Node Info and verify node info is correct (it's the same as the curl output from above)
Close Node info
Enter previously used seed. Will get "Connection Refused"
Enter new seed. Will try to connect for a couple minutes and then time out with no error.
