I bought a Deeper Connect Mini last year, "Device > System > Auto Update = on", software got stuck in version 1.1.21rel, click "Manually upgrade" get error "Invalid upgrade image". Recently it fails on error "Active tunnel number = 0".
I found the following posts, which didn't help:

1.1.22.rel Download link: https://file.ops.deeper.network/share/cb7pLYLM shows "This location can't be reached".
