N8N "Connection Lost" on desktop, but works fine on mobile (Hostinger VPS)

Hey everyone :waving_hand:
I’ve been struggling with a persistent “Connection Lost” issue on my self-hosted n8n instance (running on a Hostinger VPS).
Here’s what I’ve found so far:
The server is running fine — no crashes or Docker errors.
The n8n UI connects normally on my phone, but on my laptop it constantly shows “Connection Lost”.
I’ve already:
Disabled my antivirus and firewall.
Removed all browser extensions (AdBlock, VPNs, etc).
Tried Chrome and Firefox — same issue.
Checked WebSocket connections → it instantly disconnects on my PC.

If you’re using the hostinger 1-click install, please turn to their support to get this solved.

I am! But what I find strange is that it works on my phone and on other computers — it’s only on my computer that it doesn’t work. So I don’t know if it’s a problem with the Hostinger VPS.

I’ve already disabled the antivirus, tried different browsers, ran ipconfig /flushdns, and switched Wi-Fi networks.

It seems to be something specific to my machine!

I have a very similar problem. Not exactly Rapunzel, but it seems to stem from a missing or misconfigured WebSocket in the connections between Hostinger and N8N. That’s something I’m working on. If, like me, you use a domain via Hostinger, that’s probably the cause. N8N does not continuously receive Pings or calls from the backend, so it responds with “not connected”. My explanation is a bit confusing, sorry. If I have more information, I’ll come back and ask you a question.
