XF2.0 xhr requests canceled after 30s

[developr]

My members with slow internet have problems to upload big files or avatars.

So I tried out what could be the problem... checked the nginx config for timeouts, checked php config as well. Then I tried different forums on different php versions.

In the example a user would like to add an 3.6MB jpg as a avatar. vBulletin and XF1 works fine. They use "post" to upload the file.

Software	Method Type	PHP Version	Status
vBulletin 3	post	php5.6	ok
vBulletin 4	post	php5.6	ok
XF 1.5	post	php7.1	ok
XF 1.5	post	php7.2	ok
XF 2.0	xhr	php7.2	failed

XF2 use a xhr request to upload the files and here the request will be canceled exactly after 30s.

You can try it with the developer console in Google Chrome


Could somebody reproduce this?

Probably you need to increase maximum execution time in php.ini

Thanks for your reply.

global max_execution_time and max_input_time ist set to 60.

XF1.5 and XF2.0 use the same php.ini and only XF2 cancel the upload after 30s.

The only difference is that XF2.0 use xhr instead of post method.

Hmm, technically, XHR does use a HTTP POST request as well

Given the same file on XF 1.5 that does fail on 2.X, how long does it take your server to generate the response according network tab in chrome dev tools?

Exactly 30 seconds.

That screenshot does not answer my question:

Now I can not reproduce it. I slowdown the speed in chrome dev tools but the upload takes only 2.3s in XF1.

In vBulletin3 (php5.6) the same file takes 1.2 minutes with slow 3G settings.
