I am trying to make a simple subscription run on AWS amplify's appsync.

the subscription never fires and after about 30sec I get this error message when waiting for the sub in the appsync console:

Error: {
    "errors": [
        {
            "message": "Connection failed: Connection handshake error"
        }
    ]
}

If I recreate the call from my browser I get this error:

The only solution I found to this was to change my router...

Have no idea why it makes a difference, tried all the router setting I could think of

I used my home LTE WiFi router and kept getting this error, eventually changed to a local sim card-based router from my cell provider and it connected every time.

I have used this on many different models and works every time. The router which was failing was a Huawei B525 router, any other router doesn't give the issues...
