suddenly can't establish connection with server
hi all,
i use elephant to emit to events messages to a AWS EC2 server, everything was working fine until now, suddenly this stopped working properly. for some reason that I can't explain the connection to the server is being refused. here is the error I've been receiving. curiosity, the connection through client and the socket.io server is still working...
this is been super block on a live project, let me know what I can do.

Do you try to connect to a secure websocket server? Does it have a Let’s Encypt certificate.
Recently an intermediate root certificate has been revoked (last Thursday) and that had caused many “sudden” issues like this one. That could be a solid lead.

@guillaumepotier yes its connected to a secure websocket server and with "lets encrypt" as well. seems that the following settings are useful at least for a temporary workaround:
'context' => [ 'ssl' => [ 'verify_peer' => false, 'verify_peer_name' => false ] ]
