Browser Timeout: "This Screen will be closed."

VGMoose

@Gorzog oh wow that's very useful! Thanks! I didn't realize the timeout was so precisely at 20 minutes. This is for 45.55.142.122? It would be nice if there was some networking-level thing that could be done to stretch it out longer.

When I sleep my Switch while in the browser, I am able to get a single page to last for multiple days, but maybe that is due to the total time not yet exceeding 20 minutes. I'll need to get some specific data too.

I managed to get it to stay on the 'This screen will now be closed' thing for a day in sleep mode.

@VGMoose I updated the spreadsheet with another test putting the switch on sleep mode and more info on the system that I used

so i think the sleep process just interrupts the count down , would be worth trying the timed period with a break in sleep mode to determine if the countdown continues where it left off...

so like 10 mins browsing then go to sleep then wake it up and continue the count to see if its the same.

@pwsincd The timeout timer when in sleep mode just pauses as you can see here

pwsincd

did u continue to time it after waking ?

Gorzog

Yes, the time that I show and on the spreadsheet is the time of 5 minutes of idling then 2 minutes of sleep mode and the rest again in idle

ah ok interesting info , i assuming that the timeout isn't controlled via the browser then and from the OS somewhere

pwsincd

it may be worth trying crazy ideas like on the 20minute mark or just prior keep the keyboard open or similar system processes.

I can confirm exactly 20 min on v14.0.0 as well (waking the Switch from idle each time).

I also monitored the network requests my Switch made, and here are the log files. I have the receipts!

http log: http_timeout_log.txt
dns requests: dns_timeout_log.txt

Here you can see the full 20 minute "session". Every ~1 minute a GET request is made with the user agent "NX NIFM/00".

In between those, every ~3 seconds (!!) a HEAD request is made using the full "Mozilla/5.0 (Nintendo Switch; WifiWebAuthApplet) ..." user agent (that we also see when browing web pages).

These requests are used to determine if the captive portal has been authenticated yet. In a normal flow, as soon as you agree to the terms or log into the hotel wifi, these requests would reply with a special header (X-Organization: Nintendo) which informs the Switch that it's connected to the Internet.

After exactly 20 of the GET requests, and 401 of the HEAD requests, the browser shuts, which is expected just looking at how frequently they occur (401 = (60/3)*20+1). Although it would be interesting if instead of it being a "timeout" if it were more like "try 400 times to connect every 3 seconds, then give up".

Based on this, by counting the number of requests made, it should be possible on our end to tell when the pop up is about to appear. But there still doesn't seem like there's anything that can be done on the networking side of things to interrupt it.

Also interesting is that in the DNS log, a domain name request is only made around every minute. This means in the normal workflow, depending on how the hotspot's captive portal works, it may take up to a minute to be authenticated.

I also tested sleep (not in those logs), the network requests just stop and resume after waking the device. (Which is why counting them to know how "soon" until the timeout seems doable.)
