Starcraft2 updates not finishing

Several updates for Starcraft 2 seem to get stuck at some point while downloading. Afterwards, I can pause the update, and try to re-start it. Once re-started, the battle net app continues the installation as if it were a new update (which doesn’t make sense). Unfortunately, when continuing the update it also gets stuck and have to re-try the download.

I’m on a 16inc Macbook Pro 2019 running macOS Catalina. The BattleNet app is up to date.

Hello
Try to connect your PC to Ethernet instead of WIFI if it’s not already done.
Delete Starcraft 2 files and re-download, maybe you’ve got something corrupted.
In worst case scenario, delete new client files (see last version date) from Battle.net App and Blizzard (like new agent), in this case it will auto-update again.
