I’m having problems upgrading multiple Nextcloud instances, from multiple locations. On the upgrade process it takes a lot of time to get past the download step and on one of the upgrade process it even failed at the download step. Trying to download a zip of NC 19.0.4 on my PC it either fails completely or the download is going under 100 KB/s.
I think this thread is about the same problem, but my german is not that good
