Obsidian Sync: Error Unable to connect to server

What I’m trying to do

Use Obsidian Sync on my school/work computer.

I just started an Obsidian Sync account.
It works OK on my home computer and my personal phone (iPhone).
But it does not work on my school/work computer.

To give you some context:

  • On my school computer I have set a firewall, proxy and all those corporate limitations.
  • Obsidian can connect to internet, and update community plugins, update templates, and update the application (the Obsidian executable).
  • Obsidian was able to check that I have a vault on my Obsidian account named “Vault” and asked me for the “unlock password”
  • Before using Obsidian Sync, I was using Obsidian Git, but to make it work, I needed to setup an HTTP proxy on Git.
    • For you to understand how it works my proxy, on Git I have to configure it like the following (to make Obsidian Git work):

I thought Obsidian Sync was using an HTTP protocol, after reading the following: How to verify Obsidian Sync's end-to-end encryption - Obsidian
I was wrong.


So, I would like to know how I set the proxy on Obsidian to be able to sync?

Or how do I ask Obsidian to another URL or port, and not anything special that could be blocked on my corporate internet access? Instead of a websocket, use HTTP protocol?

I don’t know enough about network stuff to help, but is this useful? https://help.obsidian.md/Obsidian+Sync/Security+and+privacy#Managing+access+to+Obsidian+Sync+on+your+network

Thank you! Interesting link.

I just found out a few things after lots of testing:

  • I found a way to set up the corporate VPN to be able to connect to the Obsidian server
  • If I start Obsidian before I do this setup of the VPN (to Obsidian have full internet access), I get multiple database errors. So, Obsidian must re-build the index.

  • With the VPN working, Obsidian with the database build: everything works as intended.

I will keep investigating.
