Hi,

when trying to access a file that isn't a .php or .txt file in /srv/www/htdocs/... from another device in the same local net (192.168.1.x) I get in chrome browser:

This page isn't working 192.168.1.38 unexpectedly closed the connection ERR_CONTENT_LENGTH_MISMATCH

in apache2 log everything seems fine:

192.168.1.34 - - [21/Mar/2020:11:34:44 +0100] "GET /Entwicklung/karls/logo_small.png HTTP/1.1" 200 4002 "-" "Mozilla/5.0 (Linux; Android 8.1.0; DRA-L21) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Mobile Safari/537.36"

there is nothing related in apache2 error.log

I can access and display an "index.php" on the same location, also a "x.txt"-file in a subfolder of this location, but no .js, .png, .mp3 files - they all produce the error above, even when smaller in bytes than the .php file

I can access /all/ files from a browser on the same machine where apache is running. The errors occur only when accessing from another device in the same wifi-net

What could that be?

See:

Weird error: ERR_CONTENT_LENGTH_MISMATCH https://stackoverflow.com/q/28993959/3422102

Been on that page, too. But this is for typo3, I believe - or I wouldn't know where to put that "config.enableContentLengthHeader = 0"... ??? -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Daniel, I was wondering if you maybe had a another computer, maybe laptop, to try your website with? That way you might be able to limit the issue to having to do with mobile devices.

Or run a virtual machine, with a different IP in the same LAN. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

Hmm, I'm running out of things to say.

I see that text when I load it, and I have Javascript disabled by default. The text is prefaced by 'This page needs JavaScript activated to work.'

Weird. The text in red can only come from some script, it is not in the source. -- Per Jessen, Zürich (-1.3°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The website (not that sample page) makes heavy use of ajax/javascript. Therefore there is a <noscript> tag that wraps all the content into a div with style display:none in case that Javascript is disabled, and only the phrase you have seen is displayed. When Javascript is enabled the content within <noscript> is ignored, and the content shows normal. However this has no influence on the occurrence of the error I suffer. The error occurs also when loading any other file (a *.jpg, *.css ... whatever that is not .php or .txt) -- -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

No idea how this comes there, you must have such an image in your img folder.... There should be the logo-img, and when I click on it to show the img it shows me http://www.jessen.ch/img/logo_small.png which contains that string.

Aha, I did not realise it is an image. Yes, that is in fact being served from my site, I see it in the access log. Must be an internal redirect, I don't have a file called 'logo_small.png'. Hmm, interesting - at a first glance, I don't see where that could be coming from ....

...

It doesn't matter, because I cannot load any file from another device on the local net that is not *.php or *.txt. I get the described error for example for 192.168.1.38/img/logo_small.png or 192.168.1.38/css/karls.css

Huh.

It's also not a problem of the subfolder, because I also cannot load any such files that are located in any other folder. I checked the permissions of the folders, and also the apache log shows that they are loaded correctly. But in the browser I receive that error... Strange.

Very.

It runs perfectly on the same machine, and also on the online server: https://karls.es/index2.php I guess somehow apache doesn't like my local net, or it is something in my firewall? or in the router? Or???

"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." It must be something between your client and your server, between browser and apache, yes. You have stopped the firewall, right?

That's what happens when things grow old ... you forget.

The 'img/logo_small.png' was indeed rewritten to call a script called 'img.php', dated 2003. It uses 'gd' to write a text as graphic.

If I should memorize all scripts and files and photos and models I knew since 2003 I'd have to triple my internal memory capacity, approximately, but I can't find any brains-update online :-) -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

had to change in /etc/apache2/listen.conf :

Listen 80 to Listen 0.0.0.0:80

That's all. It works.

It seem to be something that freshly occurred in 15.1 and wasn't a problem before.

"Listen 80" and "Listen 0.0.0.0:80" are the same, except the latter would only listen on all IPv4 address, even if your system had IPv6.

Yes, I guess 15.1 has some problems with IPv6 that earlier versions didn't have. As the forum shows I'm not the only one who had the problem, and the good thing is that this change makes it work for me...

I'm tempted to set up a webserver on 15.1 and see if I can reproduce your problem.

Well, my problem is that your work-around does not explain the problem. If this is somehow related to IPv6, why would you have a problem when you don't have any IPv6. That's annoying :-)

I have webservers in the exact same config, with no problems. I would not want to create an issue for myself by patching them. Which kernel and apache versions are you running ?

Ha! You know what? I just updated the system this afternoon. New kernel, some apache stuff... (I did that last time about 2 weeks ago). And now, for curiosity, I switched back to the old listen.conf (with Listen 80), restarted apache - and guess what: it works... So, obviously it was a bug that was resolved now.
