SSL Socket.IO initialisation not working

[clemente-xyz]

Expected behavior

After a token transfer transaction, the new transaction event should be received by the app, and refresh balances and transactins queries automatically.

Actual behavior

For iOS devices, the web-socket connection is failing to initialise, which means that all new transactions events are not received. This causes that the app don't refresh automatically the balance and transactions of an account after the transaction is added to the blockchain.

When debugging the websocket connection, we get:

[Error: websocket error]

Steps to reproduce

1. Login to an account with balance on iOS.
2. Click on the send token button and perform a valid transaction.
3. Go back to the wallet screen and wait for the balance and transaction list to get updated with the new transaction.
4. That never happens.

Which version(s) does this affect? (Environment, OS, etc...)

5.0.0 only iOS.
