Library does not sync (Failed to get fs id list)

I wanted to sync my library to a second system. However, the seafile client always shows a network error for my main library. If I create a new library, it is syncing perfectly.

Installing Seadrive, I get the following logs:

[09/24/23 10:25:36] Cloning repo Meine Bibliothek(602eb119-2642-4c13-8eae-70183fc033b2).

[09/24/23 10:25:48] Repo 'Meine Bibliothek' sync state transition from downloading to 'error': 'Error occured in download.'.

The error occurs across different systems. However, on my initial system, where I have been syncing everything for month, Seafile has no issues with syncing. The newly installed Seadrive client still shows the same error.

Running seaf-fsck, I do not get any error and I can access everything via the web interface.

My library is 180 GB big.

that’s pretty self explanatory
do you get any error if your run curl -v

are you able to run a curl to or even ?
