This is not a local cache issue.

I second that. I have the same problem with WP 5.4

Currently I have WP 5.2.5 on PHP 7.1

@antonv so running an older version of PHP and WordPress fixed your issue? Then it seems that the issue lies with PHP 7.3 as that’s when my problems started as well.

I tried with several smaller images (less than 500kb) and the results are the same. I am running on a VPS since a couple of years back.

I’ve adjusted the input and timeout values accordingly but no change, if I upload more than one photo it freezes. Even if I upload one, wait 10 seconds and upload another, the second one freezes the system.

Curl -X https://tinypng.com returns the HTML correctly.

I am at a loss here.

I could do that, but the problems only started occurring when running WP 5.x. Before I could upload a batch of images without any Apache/PHP freezes so something must have happened with the code base during that time.

I have had similar experiences since going to WordPress 5.x and PHP 7.3 and uploading a batch of images. The site freezes for a few minutes and you get a 504 Gateway Timeout error. After a few minutes everything recovers again though, very very annoying.

Looking at the photos this is what I see after they upload:

Latest error: Error while connecting: HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)
