Timeout error

[1001v]

Hello. In my app i make several async uploads simultaneously and try to get a unique token for each of them. The problem is that i get a timeout error in most cases. I just wanted to ask, if this is a normal behavior and we can only have one token at the same time, or this is a throttle from google's servers, or this is a bug. Thank you.

Hi, I've just tried to reproduce your issue by starting 20 requests simultaneously. It looks like they will be executed sequentially, but at all each of the requests got a response with a valid token.
You may setup a demo project, where you can reproduce it, so I can look into it. But at all I'm assuming it's a limitation from Google.

Here it is. You probably should press that button a few times, but this works different everytime, sometimes even only 5 request would be enough to get errors. During requests please take a look at network activity. The interesting thing is, that when we get errors, the appropriate requests could be still finished successfully a few seconds later. You can see it on these screenshots:

A few moments later...

UPD: I think that we get errors then some connection lag happens. You can set Fast 3G network preset to see how it works.

Ok, I've tried it with your demo project. But all my requests were successfully processed (I've clicked the button ~10x).
But on your screenshots I can see that the origin of the error is the recaptcha script from Google, so I assume it's a limitation from Google (maybe even country dependent).
So maybe you can try to reach out to Google and ask them about this limitation issue.

@WipeAir just interesting, which browser did you use?

[WipeAir]

I've tested it with Chromium version 70, which one did you use?

[1001v]

@WipeAir i've tested it with some chromium browsers and firefox. The interesting thing is that this issue doesn't appear in firefox at all. I've written a letter to google about it.

Ok, that's pretty strange. Have you actually tried to reproduce it without this plugin?
Can you keep me informed about the response from Google here?

[1001v]

@WipeAir Yes, i've reproduced it with no plugins at all. I'll post something here when (i hope) i receive any response from google.

@WipeAir hello. I didn't received any response from google, but i've noticed, that the problem is gone, at least i can't reproduce it anymore. Maybe they've fixed something silently.

Hi,
that was actually as expected...
But it's nice to hear, that your problem is solved now :)
