SignalR getting Disconnected after Invoking methods multiple times

I am building a web application using ASP.NET MVC5 and decided to implementing SignalR for notifications.

I decided to also implement it for other real time client-server interactions.

I have a follow button. When clicked it invokes a follow method and sends the ID with it.

notificationsHub.server.followAction(requestId);

I'm keeping it in the same hub for now, not sure if making it in a separate hub is better.

and I bind another server method when unfollowing.

notificationsHub.server.unfollowAction(requestId);

It works fine both actions, until it reach about 5-6 clicks then the hub disconnects for no reason.

This is the JavaScript log:

jquery.signalR-2.2.1.js:82 [11:31:35 GMT+0100 (W. Central Africa Standard Time)] SignalR: notificationshub.FollowAction failed to execute. Error: Error: Send failed.

Seems that the machine I was working needed to have webSockets protocol installed, plus this issue was fixed in the latest signalR release 4 days ago.
