The different behaviour might be due to different versions of the
browsers, or it could be different configurations.

1. Is HTTPS-Only enabled? (If yes, on both systems, or only one one of
the two?)

2. If you disable HTTPS-Only and DNS-over-HTTPS on both systems, is the
behaviour the same or different?

3. For Devuan, how do you configure networking (ifupdown,
NetworkManager, or something else)?

4. Likewise Alpine


Basically, the first step is determine if the issue is in the browser or
at the network level.

Other things for that:

1. Use dig or equivalent on both systems (you'll have to install it as
it is not default). Does DNS resolve?

2. Repeat with +dnssec (e.g. is the issue with the presence or not of
DNSSEC support?).

3. Try wget and/or curl to the sites in question.
