I am upgrading from the Admin panel. There is a button that encourages me to upgrade and when I press it I get a message that files are being downloaded. After a while I will get a timeout message. I suspect that it has something to do with the host. The error message I get is this:

I searched the open issues on the Grav github. I also checked for similar issues on the forum. There were a couple that seemed similar, but were not the same.
I will probably just try to manually upgrade. Just curious if this was an easy fix?
Thanks.
