Bug Description

I attempted deploying cos-lite and I got:
❯ j deploy cos-lite --trust
ERROR resolving with preferred channel: Post "https://api.charmhub.io/v2/charms/refresh": dial tcp: lookup api.charmhub.io on
10.152.183.10:53: read udp 10.1.232.175:39939->10.152.183.10:53: i/o timeout

After that I retried and it seemed to work well, only a few charms were stuck in waiting/installing agent. Example for grafana/0:

09 Nov 2022 09:47:54+01:00 juju-unit allocating
09 Nov 2022 09:47:54+01:00 workload waiting installing agent
09 Nov 2022 09:55:25+01:00 workload waiting agent initialising
09 Nov 2022 09:55:28+01:00 workload maintenance installing charm software
09 Nov 2022 09:55:28+01:00 juju-unit executing running install hook
09 Nov 2022 09:55:31+01:00 juju-unit executing running grafana-source-relation-created hook

attaching the controller logs.

Grafana logs are as follows:
