If a token decryption failed, it will emit a HTTP 500.
We should not retry Axios in this case but rather fail.
Note: a token decryption failed should not throw a HTTP 500 but another error code (HTTP 401?)
So maybe this fix is plainly wrong.
Now, if the first pusher request fails, a waiting message will be displayed and the application will reconnect when the pusher comes back alive or the network connection is established again.
