I recently installed Apache 2.4.27 and Nextcloud 12.0.2 on Arch Linux using the available offical packages.
\nAfter enabling http2 I found that larger downloads from Nextcloud were failing after a couple of hundred megabytes. The download just stops until there is a timeout and the browser shows a failure. The server logs showed no error at all but infact a nice http 200 success code.<\/p>\n
After switching between php-fpm and an fcgi wrapper, between mpm worker and mpm event I gave it a test and disabled http2 again and voila the downloads were working just fine.<\/p>\n
And indeed there are some issues to be found when searching the net and especially https:\/\/github.com\/owncloud\/core\/issues\/26753<\/a> sounded very familiar.<\/p>\n After fiddling with some of the mod_http2 options I finally increased the H2StreamMaxMemSize Directive<\/a> to an arbitrary but significantly higher value: No more failures after that, even when downloading multiple files concurrently from different devices! No more stuck files and perfect happyness \ud83d\ude09<\/p>\n","protected":false},"excerpt":{"rendered":" I recently installed Apache 2.4.27 and Nextcloud 12.0.2 on Arch Linux using the available offical packages.
