I suggest as an alternative. try MQTT-JSON PubSub form Ignition GW. It's very easy for you because you have the tags and alarms ready to PubSub. Theoretically, unlimited nr of clients can PubSub from either side on different topics on the same port. I have all the building blocks to do it from Ignition server. I can share the details with you to speed up your work. To understand what i mean, check out this post.
FYI, the index.html file is using "mqttws31.js" library.
