Plugin install fails in webinterface, works via SSH

Hello, I'm an experienced user by now, had OctoPi on my old printer for years. I just set up another one for the Voron 2.4 I just built and have this strange problem with plugins:
If I use the Plugin manager to install a new plugin, it shows the install popup with the usual "Installing plugin "x" from https://github.com/y/z/archive/master.zip..." and then hangs indefinitely.
If I try to install the same plugin via SSH, it works, but I get the "WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='codeload.github.com', port=443): Read timed out. (read timeout=15)")': /jneilliii/OctoPrint-AutoTerminalInput/zip/master" message at the beginning.
OctoPrint version : 1.5.3
OctoPi version : 0.18.0
Pi 4, 2GB RAM
Klipper
Everything else seems to work. This is a recurring problem, going on for days now. Currently I have camera disabled (still in the mail :wink: ), the rest is stock. Anybody has any ideas? The logs for plugin manager and software update are empty, main log has this to say (from startup to page reload after stuck install popup):
