Hello everyone,
Since September 9th, all my n8n automations hosted on a Hostinger VPS with Cloudron started to hang for several minutes and then fail with:
"The connection timed out"
This happens on:
API calls to Teamtailor (previously worked fine for months),
API calls to Google Drive (same issue).
Key points:
My setup had been running smoothly for over 2 months.
On Sept 9th, both my n8n apps started failing simultaneously.
Tests inside the container show:
curl -6 https://api.teamtailor.com → host cannot be resolved (IPv6 fails).
curl -4 and node -e https.get(...) → immediate response over IPv4 (expected 404).
I added the environment variable NODE_OPTIONS=--dns-result-order=ipv4first and restarted containers.
Confirmed with printenv → variable is applied.
However, workflows in the n8n UI still hang for ~10 minutes before timing out.
Hostinger support says:
They cannot intervene directly (self-managed VPS),
Suggested disabling IPv6 at VPS level or restoring a backup from before Sept 9.
My questions:
Has anyone else on Cloudron/n8n experienced similar issues since Sept 9 (especially related to IPv6)?
Is it safe/recommended to fully disable IPv6 on the VPS (via sysctl) to force IPv4 only?
Could a recent update of Cloudron/n8n explain this behavior (workflows waiting on IPv6 instead of quickly switching to IPv4)?
Any feedback or advice would be greatly appreciated
