/sync isn't working properly

[Nurmuhammad032]

So, sometimes, I /sync endpoint takes more time than limit (50s, 1m), then I get cancelled status. After getting cancelled status from Chrome network tab, /sync stops, then never sending sync request again to get new updates until reload the webpage. I've been strugling this issue for a month, do you know any information related to the problem?
I have no idea the problem belongs to the server (Synapses) or client, let me know if you know the issue..

The (time) limit is a property we send to the server for how long it is to wait before returning if there is no data, if it takes longer than that it'd be an issue in the server not complying with the Matrix spec

element-web certainly does start syncing again even if the sync request times out, so this doesn't sound quite right

yes, element-web works quite well. i think, we have to check backend side. thank you both of them!
