Initial sync keeps failing v2.4.116

[tkral-ts]

Dear all,
trying to sync a new MISP instance from misppriv.circl.lu, but it repeatedly fails after some time pulling events. It fails using GUI button or cake CLI the same. When I start the sync process manually, it works few hundreds/thousands events to fail again.

I have updated to the last git version before the last fail happened.
