Unable to determine precise nature of "proxy error" message

Nextcloud version (eg, 10.0.2): 10.0.2
Operating system and version (eg, Ubuntu 16.04): Scientific Linux 7.2
Apache or nginx version (eg, Apache 2.4.25): 2.4.6
PHP version (eg, 5.6): 5.4.16
Is this the first time you’ve seen this error and can you replicate it?: See the issue and can replicate when specific conditions are met.

The issue you are facing: Modified settings and configuration to allow large file uploads. No errors or issues when uploading anything 10GB or smaller. Currently max file size upload is set to 20GB, but after uploading a file between 10 and 20GB I see a message about a “proxy error”. However, if I click on All Files (after allowing sufficient time for the file to be moved from the temp directory to the user data directory) the file is present. Other tester was able to download the file and confirm via MD5Sum that it matches the file uploaded.

The output of your Nextcloud log in Admin > Logging: No message regarding proxy error in log

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php $CONFIG = array ( 'instanceid' => REMOVED 'passwordsalt' => REMOVED 'secret' => REMOVED 'trusted_domains' => array ( 0 => 'localhost', 1 => REMOVED, 2 => REMOVED, ), 'datadirectory' => '/pub/nextcloud/data', 'overwrite.cli.url' => REMOVED, 'dbtype' => 'mysql', 'version' => '', 'dbname' => 'nextcloud_db', 'dbhost' => 'localhost', 'dbport' => '', 'dbtableprefix' => 'oc_', 'dbuser' => REMOVED 'dbpassword' => REMOVED 'logtimezone' => 'UTC', 'installed' => true, 'ldapIgnoreNamingRules' => false, 'ldapProviderFactory' => '\\OCA\\User_LDAP\\LDAPProviderFactory', 'loglevel' => 0, ); The output of your Apache/nginx/system log in `/var/log/____`: Unable to find related error message. At present this looks more like a bug rather than an actual error, but as this is a proof-of-concept for a potentially larger deployment I would like to determine the nature of the error and how it can eliminated. --- Remember, this information may be requested if it isn't supplied; for fastest response please provide as much as you can :heart: Feel free to use a pastebin service, otherwise log files can be indented with 4 spaces on each line to present them in a friendlier way on the forum.

It appears that the solution to this problem was to upgrade to PHP 5.6 and install Nextcloud 11.
