Websockets are working fine, everything seems to work except for anything that vaultwarden needs to reach out to like version checks, NTP and push notifications.

In the log there is error setting up push:

[2023-10-02 00:18:49.867][vaultwarden::api::push][ERROR] Error getting push token from bitwarden server: error sending request for url (https://identity.bitwarden.com/connect/token): error trying to connect: dns error: No connections available

I can curl https://identity.bitwarden.com/connect/token from the server and it reaches it without issue. This all used to work fine it is just the last few Bitwarden versions this seems to happen, never had any issues in the past.

SMTP reaches out no worries to send emails through Microsoft 365.

Using nginx as reverse proxy, was using my own config but I have switched to the nginx config provided by @BlackDex in the proxy examples.

FWIW I also see this in the vaultwarden log:
[2023-10-02 00:59:53.441][trust_dns_resolver::system_conf::unix][WARN] no nameservers found in config

But DNS is working fine on the server.

I suspect this is going to be a DNS issue within Vaultwarden, but why does it only pop up in current versions did something change?
