Error: Failed container creation: local error: tls: bad record MAC

When I try to download a new image

lxc launch ubuntu:19.10 test
Creating test
Retrieving image: rootfs: 11% (9.58MB/s)

This error come during downloading.

Error: Failed container creation: local error: tls: bad record MAC

One thing I see is, that it downloads up to 100% but then it starts again by 0% and then at arount 10% this error comes.

It worked before! I have created e.g. a Ubuntu 18.04 container but now it does not work anymore. I think not, that I changed something in my setup.

Can anyone please help?
