Whonixcheck issues, slowness

I had to reinstall Whonix. Now whonixcheck is really unstable and slow compared to the previous installation. I was so happy about whonix 13 and how much quicker and smoother it ran but now I’m facing more issues with whonixcheck. Too often do I get Socks errors, errors on whonix news, on the update status. It’s nothing, because when I run it a second time or debug it, it’s totally fine. As I mentioned it is a lot slower.
Also apt-get update often gives me an errod about hash-sum mismatch amongst others. After a few tries incl. --fix-missing it’s fine.
It’s not anything ubearable but I’d like to know how there can be such a difference given it’s the same system with the same set up.
