PUN web socket connection error

Options
Hey, Ive been using PUN without any issues for the most part, but when I try to run my project from a WEBGL build sometimes it manages to connect to the master server but sometimes it does not and throws this error:
Exiting receive thread (inside loop). Server: wss://GCASH065.exitgames.com:19091:0 Error: An exception has occurred while receiving.

UnityEngine.Debug:LogError(Object)
Photon.Realtime.LoadBalancingClient:DebugReturn(DebugLevel, String) (at Assets/Photon/PhotonRealtime/Code/LoadBalancingClient.cs:2509)
ExitGames.Client.Photon.<ReceiveLoop>d__12:MoveNext() (at Assets/Photon/PhotonLibs/WebSocket/SocketWebTcp.cs:317)
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

If I'm not mistaken it's because my project is supposedly missing a plug in but said plugin (WebSocket) is indeed in the project, there's also one called PhotonWebSocket that's in the project.

¿Has anyone ran into a similar situation?
