Hello all, my first post! I have similar problem. Didn’t find any glue from server side logs, but linux client log is filled with entries like this:
[04/24/21 18:52:45] http-tx-mgr.c(1172): Parse response failed: ‘[’ or ‘{’ expected near ‘<’.
[04/24/21 18:52:45] clone-mgr.c(864): Transition clone state for 51885218 from [check server] to [error]: check server.
I installed seafile in folder, example.tld/seafile. I’m running Yunohost on raspberry pi 4b.
SOLVED! Just fix the paths like described here: [SOLVED]Can't upload files to seafile since yunohost 4.1 update
