iOS cannot access Self-hosted

I see that there has been an issue with people making use of the Bitwarden iOS Client when upgrading to vaultwarden (say from bitwarden). I am running vaultwarden from ContainerManager via my Synology NAS.

I am having troubles accessing vaultwarden from my iOS device. I think it’s due to a timeout with connection.

Server info:
Self-hosted with SSL from LetsEncrypt

Server Installed Ok - 1.32.6
Server Latest - 1.32.6
Web Installed - 2024.6.2c
Database - SQLite: 3.46.0

I can access the server from my desktop using the URL(domain) but also from the Bitwarden browser extensions.

I cannot access it at all on my iPhone.
I’ve have WiFi on and and WiFi off and cannot access the URL or via the Bitwarden iOS app.
I do not have Privacy Relay enabled either.

I do have an internal DNS server running for split DNS but that I don’t think is an issue as when I drop into a terminal the URL I use resolves to the proper IP still (external) - Disabling WiFi of course takes the split DNS out of the question.

Anyone else have issues trying to connect after upgrading to the lastest Vaultwarden?
