The Red Hand Files failed with error 0

Just noticed that this is failing and no one else has reported it.

HttpException: cURL error HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1): 92 (https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://www.theredhandfiles.com in lib/contents.php line 308

im unable to reproduce. im on non-docker debian 11, php 7.4.33 and curl 7.74.0 (x86_64-pc-linux-gnu) libcurl/7.74.0

reminds me of #3249

I cannot reproduce this issue either. Tested with php 8.2.6 development server and libcurl 8.0.1.

@sdenaro What libcurl version are you running? Is the issue still present?

[sdenaro]

PHP 7.4.33 (cli) (built: Feb 22 2023 20:07:47) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.33, Copyright (c), by Zend Technologies

Using:

php -r 'foreach (get_loaded_extensions() as $extension) echo "$extension: " . phpversion($extension) . "\n";'|grep curl

I get

curl: 7.4.33

It seems the server is not the culprit here, at least Firefox and curl are using HTTP/2 and working fine in our testing. Maybe the client (curl version) is the culprit here? Ideally you can try with a modern curl version.
A workaround would be to set the HTTP version to 1.1, which we don't wanna do by default.

I also found hints that the culprit might be a HTTP header we send and the web server is not happy about that, leading to that error...

[sdenaro]

I think I am well overdue to upgrade to php8.x as was as libcurl. I will try that and close the ticket with a note detailing if that worked.

[sdenaro]

looks like switching to php8.2 plus a current libcurl was enough to fix this.
