I'm experiencing regular downtime on my Railway deployment, approximately 2x per day with outages lasting 2-4 minutes each. This is being detected by Uptime Kuma (running 1-minute checks), and I've manually verified the downtime is actually occurring.
I haven't made any recent changes to my application or deployment configuration. Any ideas what could be causing this?

More information:
Running 3 containers:
- Django
- Redis
- Postgresql

I also have Sentry running on my server, but it received zero errors.
I run it through Cloudflare with 'FULL' mode on TLS.

From Uptime doctor:
DOWN at Feb 03 2026 05:40 PM (EU/Central)
Err: HTTP/1.1 525 <none>

DOWN at Jan 30 2026 01:50 AM (EU/Central)
Err: HTTP/1.1 520 <none>

logs (16:40 is the outage for a little bit):

Sometimes things are just weird try turning it off and on again and see if that helps:

  • remove + re-add the custom domain in Railway

  • toggle Cloudflare proxy off/on (forces CF to re-pull origin details)

If that doesn't help please also provide logs from your services from around those downtimes

Any chance someone from railway could help take a look at this? No one seems to be able to figure it out. I want to upgrade to ‘pro’ tier, but this issue is really holding me back.
Just went down again at ~10:45
