What are these GETs doing?

[lyojo]

They keep loading,which are time consuming!

[julian]

@lyojo It looks like they're xhr-polling calls, which are made periodically to check for new events from the server. Normally, swift.gg (and NodeBB in general) uses websockets, so perhaps your browser or ISP does not support websockets?

@julian How can I know wether My ISP support websockets or not?The return status is 200,does it mean websockets works well?

@julian I am unable to hit WS on swift.gg as well. (Firefox). I think @lyojo you may not have configured your proxy correctly, are you using nginx or apache? Please consult:

https://docs.nodebb.org/en/latest/configuring/proxies/apache.html
or
https://docs.nodebb.org/en/latest/configuring/proxies/nginx.html

And see if you've set up correctly. BTW, to tell if your ISP does support WS, you can always just check this forum to see if you're reproducing the same issue. If not, then it's a configuration issue on your end

Yes, the polling 200 status indicates nothing is wrong. Everything you're seeing is completely normal of nodes Socket.IO.

Furthermore, polls are done on port 80 http, so it would never be blocked. Webscoket traffic in general is done ona range of ports, none of which ISP's filter (I've worked for an ISP). The only port I know that SOME NorthAmerican ISP's block is SMPT incoming and even that is rare.
